Every atom in your body came from a star that exploded. And, the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics: You are all stardust. You couldn’t be here if stars hadn’t exploded, because the elements - the carbon, nitrogen, oxygen, iron, all the things that matter for evolution and for life - weren’t created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way for them to get into your body is if those stars were kind enough to explode. So, forget Jesus. The stars died so that you could be here today.
The knowledge that the atoms that comprise life on earth - the atoms that make up the human body, are traceable to the crucibles that cooked light elements into heavy elements in their core under extreme temperatures and pressures. These stars- the high mass ones among them- went unstable in their later years- they collapsed and then exploded- scattering their enriched guts across the galaxy- guts made of carbon, nitrogen, oxygen, and all the fundamental ingredients of life itself. These ingredients become part of gas clouds that condense, collapse, form the next generation of solar systems- stars with orbiting planets. And those planets now have the ingredients for life itself. So that when I look up at the night sky, and I know that yes we are part of this universe, we are in this universe, but perhaps more important than both of those facts is that the universe is in us. When I reflect on that fact, I look up- many people feel small, cause their small and the universe is big. But I feel big because my atoms came from those stars.
And when you look at the sky you know you are looking at stars which are hundreds and thousands of light-years away from you. And some of the stars don’t even exist anymore because their light has taken so long to get to us that they are already dead, or they have exploded and collapsed into red dwarfs. And that makes you seem very small, and if you have difficult things in you life it is nice to think that they are what is called negligible, which means they are so small you don’t have to take them into account when you are calculating something.
Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there--on a mote of dust suspended in a sunbeam.
Medicine rests upon four pillars—philosophy, astronomy, alchemy, and ethics. The first pillar is the philosophical knowledge of earth and water; the second, astronomy, supplies its full understanding of that which is of fiery and airy nature; the third is an adequate explanation of the properties of all the four elements—that is to say, of the whole cosmos—and an introduction into the art of their transformations; and finally, the fourth shows the physician those virtues which must stay with him up until his death, and it should support and complete the three other pillars.
The time will come when diligent research over long periods will bring to light things which now lie hidden. A single lifetime, even though entirely devoted to the sky, would not be enough for the investigation of so vast a subject... And so this knowledge will be unfolded only through long successive ages. There will come a time when our descendants will be amazed that we did not know things that are so plain to them... Many discoveries are reserved for ages still to come, when memory of us will have been effaced.
If the people of Europe had known as much of astronomy and geology when the bible was introduced among them, as they do now, there never could have been one believer in the doctrine of inspiration. If the writers of the various parts of the bible had known as much about the sciences as is now known by every intelligent man, the book never could have been written. It was produced by ignorance, and has been believed and defended by its author. It has lost power in the proportion that man has gained knowledge. A few years ago, this book was appealed to in the settlement of all scientific questions; but now, even the clergy confess that in such matters, it has ceased to speak with the voice of authority. For the establishment of facts, the word of man is now considered far better than the word of God. In the world of science, Jehovah was superseded by Copernicus, Galileo, and Kepler. All that God told Moses, admitting the entire account to be true, is dust and ashes compared to the discoveries of Descartes, Laplace, and Humboldt. In matters of fact, the bible has ceased to be regarded as a standard. Science has succeeded in breaking the chains of theology. A few years ago, Science endeavored to show that it was not inconsistent with the bible. The tables have been turned, and now, Religion is endeavoring to prove that the bible is not inconsistent with Science. The standard has been changed.
I have realized; it is during the times I am far outside my element that I experience myself the most. That I see and feel who I really am, the most! I think that's what a comet is like, you see, a comet is born in the outer realms of the universe! But it's only when it ventures too close to our sun or to other stars that it releases the blazing "tail" behind it and shoots brazen through the heavens! And meteors become sucked into our atmosphere before they burst like firecrackers and realize that they're shooting stars! That's why I enjoy taking myself out of my own element, my own comfort zone, and hurling myself out into the unknown. Because it's during those scary moments, those unsure steps taken, that I am able to see that I'm like a comet hitting a new atmosphere: suddenly I illuminate magnificently and fire dusts begin to fall off of me! I discover a smile I didn't know I had, I uncover a feeling that I didn't know existed in me... I see myself. I'm a shooting star. A meteor shower. But I'm not going to die out. I guess I'm more like a comet then. I'm just going to keep on coming back.
My days I devote to reading and experiments in chemistry, and I spend many of the clear nights in the study of astronomy. There is, though I do not know how there is or why there is, a sense of infinite peace and protection in the glittering hosts of heaven. There it must be, I think, in the vast and eternal laws of matter, and not in the daily cares and sins and troubles of men, that whatever is more than animal within us must find its solace and its hope.
If the stars should appear one night in a thousand years, how would men believe and adore; and preserve for many generations the remembrance of the city of God which had been shown! But every night come out these envoys of beauty, and light the universe with their admonishing smile.
Science is opposed to theological dogmas because science is founded on fact. To me, the universe is simply a great machine which never came into being and never will end. The human being is no exception to the natural order. Man, like the universe, is a machine. Nothing enters our minds or determines our actions which is not directly or indirectly a response to stimuli beating upon our sense organs from without. Owing to the similarity of our construction and the sameness of our environment, we respond in like manner to similar stimuli, and from the concordance of our reactions, understanding is born. In the course of ages, mechanisms of infinite complexity are developed, but what we call 'soul' or 'spirit,' is nothing more than the sum of the functionings of the body. When this functioning ceases, the 'soul' or the 'spirit' ceases likewise.I expressed these ideas long before the behaviorists, led by Pavlov in Russia and by Watson in the United States, proclaimed their new psychology. This apparently mechanistic conception is not antagonistic to an ethical conception of life.
We ought to regard the present state of the universe as the effect of its antecedent state and as the cause of the state that is to follow. An intelligence knowing all the forces acting in nature at a given instant, as well as the momentary positions of all things in the universe, would be able to comprehend in one single formula the motions of the largest bodies as well as the lightest atoms in the world, provided that its intellect were sufficiently powerful to subject all data to analysis; to it nothing would be uncertain, the future as well as the past would be present to its eyes. The perfection that the human mind has been able to give to astronomy affords but a feeble outline of such an intelligence.
Philosophy [nature] is written in that great book which ever is before our eyes -- I mean the universe -- but we cannot understand it if we do not first learn the language and grasp the symbols in which it is written. The book is written in mathematical language, and the symbols are triangles, circles and other geometrical figures, without whose help it is impossible to comprehend a single word of it; without which one wanders in vain through a dark labyrinth.
National boundaries are not evident when we view the Earth from space. Fanatical ethnic or religious or national chauvinisms are a little difficult to maintain when we see our planet as a fragile blue crescent fading to become an inconspicuous point of light against the bastion and citadel of the stars.
The reappearance of the crescent moon after the new moon; the return of the Sun after a total eclipse, the rising of the Sun in the morning after its troublesome absence at night were noted by people around the world; these phenomena spoke to our ancestors of the possibility of surviving death. Up there in the skies was also a metaphor of immortality.
At the very moment that humans discovered the scale of the universe and found that their most unconstrained fancies were in fact dwarfed by the true dimensions of even the Milky Way Galaxy, they took steps that ensured that their descendants would be unable to see the stars at all. For a million years humans had grown up with a personal daily knowledge of the vault of heaven. In the last few thousand years they began building and emigrating to the cities. In the last few decades, a major fraction of the human population has abandoned a rustic way of life. As technology developed and the cities were polluted, the nights became starless. New generations grew to maturity wholly ignorant of the sky that had transfixed their ancestors and that had stimulated the modern age of science and technology. Without even noticing, just as astronomy entered a golden age most people cut themselves off from the sky, a cosmic isolationism that ended only with the dawn of space exploration.
The near side of a galaxy is tens of thousands of light-years closer to us than the far side; thus we see the front as it was tens of thousands of years before the back. But typical events in galactic dynamics occupy tens of millions of years, so the error in thinking of an image of a galaxy as frozen in one moment of time is small.
The others would then fall silent and she would continue about doped gallium arsenide detectors, or the ethanol content of the galactic cloud W-3. The quantity of 200-proof alcohol in this single interstellar cloud was more than enough to maintain the present population of the Earth, if every adult were a dedicated alcoholic, for the age of the solar system. The tamada had appreciated the remark.
Then they wondered if there were men in the stars. Why not? And as creation is harmonious, the inhabitants of Sirius ought to be huge, those of Mars middle-sized, those of Venus very small. Unless it is the same everywhere. There are businessmen, police up there; people trade, fight, dethrone their kings. Some shooting stars suddenly slid past, describing a course in the sky like the parabola of a monstrous rocket. ‘My Word,’ said Bouvard, ‘look at those worlds disappearing.’ Pecuchet replied: ‘If our world in its turn danced about, the citizens of the stars would be no more impressed than we are now. Ideas like that are rather humbling.’ ‘What is the point of it all?’ ‘Perhaps there isn’t a point.’ ‘Yet…’ and Pecuchet repeated the word two or three times, without finding anything more to say.
When I look at the night sky, I'm overwhelmed by the enormity of the universe. But this doesn't make me question my significance in God's eyes, no. Instead, it makes me drop to my knees in awe of God. If God created all of this, how powerful must He be to be able to manage and sustain all of it? God has to have enormous power to manage the entire cosmos. How mighty must He be to hold this massive universe in the palm of His hand?
The Earth is cylindrical, three times as wide as it is deep, and only the upper part is inhabited. But this Earth is isolated in space, and the sky is a complete sphere in the center of which is located, unsupported, our cylinder, the Earth, situated at an equal distance from all the points of the sky.
You would hardly think, at first, that horrid monsters lie up there waiting to be discovered by any moderately penetrating mind--monsters to which those of the oceans bear no sort of comparison."What monsters may they be?"Impersonal monsters, namely, Immensities. Until a person has thought out the stars and their inter-spaces, he has hardly learnt that there are things much more terrible than monsters of shape, namely, monsters of magnitude without known shape. Such monsters are the voids and waste places of the sky... In these our sight plunges quite beyond any twinkler we have yet visited. Those deep wells for the human mind to let itself down into, leave alone the human body! and think of the side caverns and secondary abysses to right and left as you pass on!...There is a size at which dignity begins," he exclaimed; "further on there is a size at which grandeur begins; further on there is a size at which solemnity begins; further on, a size at which awfulness begins; further on, a size at which ghastliness begins. That size faintly approaches the size of the stellar universe. So am I not right in saying that those minds who exert their imaginative powers to bury themselves in the depths of that universe merely strain their faculties to gain a new horror?
There's no obvious reason to assume that the very same rare properties that allow for our existence would also provide the best overall setting to make discoveries about the world around us. We don't think this is merely coincidental. It cries out for another explanation, an explanation that... points to purpose and intelligent design in the cosmos.
There are three known planets in the PSR B1257 system, which have been named Draugr, Poltergeist and Phobetor. Poltergeist was the first to be discovered. I know, I was curious about their names as well. Poletrgeist means "pounding ghost". The draugr are the unded in Norse legends who live in their graves. And Phobetor is the personification of nightmares, and the son of Nyx, Greek goddess of the night.Astronomers are goths.
If you still believe that aliens would travel hundreds of light years to carve temporary graffiti in our wheat, then your imagination is one of the seven wonders of the world, and should be bronzed.
That black, maddening firmament; that vast cosmic ocean, endlessly deep in every direction, both Heaven and Pandemonium at once; mystical Zodiac, speckled flesh of Tiamat; all that is chaos, infinite and eternal. And yet, it's somehow the bringing to order of this chaos which perhaps has always disturbed me most. The constellations, in their way, almost bring into sharper focus the immensity and insanity of it all - monsters and giants brought to life in all their gigantic monstrosity; Orion and Hercules striding across the sky, limbs reaching for lightyears, only to be dwarfed by the likes of Draco, Pegasus, or Ursa Major. Then bigger still - Cetus, Eridanus, Ophiuchus, and Hydra, spanning nearly the whole of a hemisphere, sunk below the equator in that weird underworld of obscure southern formations. You try to take them in - the neck cranes, the eyes roll, and the mind boggles until this debilitating sense of inverted vertigo overcomes you...
Uncle Yuichi: Something's moving up there? Hmm... I don't see anything. It was probably a satelite. Punpun (with gums flapping): Could I have discovered a new planet?!(long pause) Yuichi: Yes! This could be a great discovery! If it really is a new planet... It'll be called Planet PunPun! Punpun (slobbering again): Do you think I'll win the Nobel Prise?! Yuichi: You sure are a greedy kid.
At the age of 46 I was starting to see the appearance of rainbow halos and starbursts around bright nighttime lights, problems reading small print, focusing issues with my eyes, and image recognition issues. I had been exposed to bright high powered 20 watt scattered sodium LASER light a decade earlier in very high altitude astronomy.
n every culture, the sky and the religious impulse are intertwined. I lie back in an open field and the sky surrounds me. I’m overpowered by its scale. It’s so vast and so far away that my own insignificance becomes palpable. But I don’t feel rejected by the sky. I’m a part of it - tiny, to be sure, but everything is tiny compared to that overwhelming immensity. And when I concentrate in the stars, the planets, and their motions, I have an irresistible sense of machinery, clockwork, elegant precision working on a scale that, however lofty out aspirations, dwarfs and humbles us.
This had not endeared him to exobiologists such as Dr Perera, who took exactly the opposite view. To them, the only purpose of the Universe was the production of intelligence, and they were apt to talk sneeringly about purely astronomical phenomena, 'Mere dead matter' was one of their favourite phrases.
He could sense in her the same spirit that ran in his veins. They were people with independent minds. They were not clerks at desks. They preferred to act. Accomplish something. They were rushing to reach the end. Such people need to be left alone. They are used to the darkness, the silence, the waiting. They belong to the same family. That of leopards.
Policemen are often confronted with situations which baffle them at first. A certain crime scene may seem meaningless, but they have to derive some meaning out of it. They have to connect the dots, find the links, delve into its history, look for evidence, come up with a zillion theories and arrive at truth. The thing is, truth is always stranger than fiction.
At the age of 45, most days in Tucson were spent feeling like I was on the summit of Mauna Kea, as I was exhibiting debilitating health symptoms that corresponded to what I saw at very high altitude. I was later to find that I had erratic low blood oxygen levels after almost a decade of high altitude work.
We have yet to encounter an observable astronomical phenomenon that require a supernatural element to be added to a model in order to describe the even...Observations in cosmology look just as they can be expected to look if there is no God.
After a decade of working in high altitude astronomy the medical profession discovered that I had a hole in my heart, erratic low blood oxygen levels and brain issues. Heart, lung and brain problems appear to be long term known adverse health aspects of high altitude work and unnatural electromagnetic radiation exposures.
The Greeks made Space the subject-matter of a science of supreme simplicity and certainty. Out of it grew, in the mind of classical antiquity, the idea of pure science. Geometry became one of the most powerful expressions of that sovereignty of the intellect that inspired the thought of those times. At a later epoch, when the intellectual despotism of the Church, which had been maintained through the Middle Ages, had crumbled, and a wave of scepticism threatened to sweep away all that had seemed most fixed, those who believed in Truth clung to Geometry as to a rock, and it was the highest ideal of every scientist to carry on his science 'more geometrico.
It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another and to preserve and cherish the pale blue dot, the only home we've ever known.
Snow cleaning of the world's largest telescope mirrors was an impressive sight. The optics technicians would climb into a huge telescopic boom lift and spray immense clouds of cold carbon dioxide snow and gas onto the ten meter diameter mirrors high above the floor indoors. It would cause some of the accumulated dirt to magically fall off, leaving it less dirty.
I study Astronomy because it is the loftiest form of science available. It is the highest possible reaches that we can go to with knowledge and understanding. Every day, we get to look into infinity, into the everlasting, into time, space, space-time and into both the past and the future. Every day, we redefine what exists; we dance on the borders of reality and the unreal. I hardly even dare say the word, “unreal.” We have yet to prove that word.
The quiet brings to mind the multitude of men and women living out their days in solitude—each convinced that their fears and wants are unique to themselves—and she longs to press herself into their fold and be counted among those whose lives are meshed with the turning of the world.
Sometimes he counts himself to sleep by imagining the miles between stars like the succession of footsteps cleaving him from his home, as if mastering the distance in thought might blunt the separation. But if a man cannot return to the place of his birth, then what is there to stay his restless feet? What center will hold him from wandering endlessly? It should not be so difficult, he thinks, to know one’s place in the order of things.
...but at night when he turns the awkward [telescope] skyward, he catches his breath at the clarity of the image and the vast populations of stars unknown to him until then, the riotous glittering in the dark crevices between constellations, a convocation of bright spirits waiting to be found.
Sketches of mad skies spilling stars caught in spiraling gyres, diagrams for constructing sextants tall as a man and armillary spheres to mimic the motion of the cosmos. He decides that he must have all of it, that he will cram the little observatory with maps and charts, clocks and compasses, and instruments for bringing the sky nearer.
He tracks the rise and fall of the glittering darkness thronged with specks and tendrils of luminous secrets. Falling stars crackle in the cold air and prickle his skin. They flash in the corner of his vision where the eye’s discernment of light and shadow is most acute.
What has been his cause for searching the heavens day and night, for testing the limit of his reach hour by hour like a man trapped inside an expanding balloon? The reasons were as various as the days they consumed: to grasp the workings of the universe, to find something more beyond earth's fretful compass, to put his name to a discovery and secure fame's immortality, to be able to point to a map and proclaim simply: here I am.

Is this not the very thing that drives an adventurous man to navigate uncharted oceans, to traverse continents and mountains, to pilot virgin estuaries and hidden coves—this promise of inscribing a name steadfast upon what he finds? There are few parcels of earth left to be claimed; yet even as the known world shrinks, the heavens grow ever more infinite. An explorer of the skies need never leave his home or fret over the swiftness of other expeditions; he might give whatever name he chooses to any new thing that wanders into his view.
But if watching the sky is to be his duty, how should he begin? Now and then he has spotted one of the five bright planets or recognized a constellation, but he knows little about the turning of the heavens. When he contemplates the great distances between this and that, and the vast multitude of solitary objects spread over the celestial dome, he cannot fathom how one goes about searching for what is yet unknown.
In the library of the observatory in Ondrejov, above Prague, I once found a catalogue of stars that astounded me. It had hundreds of pages with tables of stars that had been observed and confirmed to exist. Towards the end there was a table of stars thought to have been observed but confirmed to not exist. But to my astonishment, at the back of the volume I found a list of stars which had never been observed and did not exist. Perhaps the most amazing thing about the universe is that we could create an infinite catalogue of things, worlds and beings that no one has seen and which do not exist. Each story in the realm of fiction is a small part of that catalogue.
The future of the next generation relies on astronomers obtaining a full understanding ofthe rapidly changing human environmental conditions and the halting of biologically toxic corporategovernment policies. The overloading of the electromagnetic environment is one of these disastrouspolicies that must stop.
What has been done is little—scarcely a beginning; yet it is much in comparison with the total blank of a century past. And our knowledge will, we are easily persuaded, appear in turn the merest ignorance to those who come after us.
[Giordano] Bruno died, despised and suffering, after eight years of agony. From that moment, his works have attracted interest, and he has long been recognized as an important figure in the development of modern thought. Nevertheless, few are familiar with the many and often bewildering pages of his writings. His Italian works have their place in the history of Italian literature. The Latin works in prose and verse are much more bulky and diffuse, but the few who grapple with them are rewarded by passages of great beauty and eloquence.
There are even some stars so remote that their light will reach the Earth only when Earth itself is a dead planet, as they themselves are dead, so that the living Earth will never be visited by that forlorn ray of light, without a living source, without a living destination. Often on fine nights when the park of this establishment is vacant, I amuse myself with this marvelous instrument (telescope). I go upstairs, walk across the grass, sit on a bench in the Avenue of Oaks – and there, in my solitude, I enjoy the pleasure of weighing the rays of dead stars.
Light and the human is poorly understood by the astronomicalprofession, with many astronomers not understanding which light bulbs they should have in their ownhomes and offices! It is embarrassing that astronomers do not understand the many forms of artificiallighting that they are exposed to every day and how it affects them.
There is a wide yawning black infinity. In every direction the extension is endless, the sensation of depth is overwhelming. And the darkness is immortal. Where light exists, it is pure, blazing, fierce; but light exists almost nowhere, and the blackness itself is also pure and blazing and fierce. But most of all, there is very nearly nothing in the dark; except for little bits here and there, often associated with the light, this infinite receptacle is empty.This picture is strangely frightening. It should be familiar. It is our universe.Even these stars, which seem so numerous, are, as sand, as dust, or less than dust, in the enormity of the space in which there is nothing. Nothing! We are not without empathetic terror when we open Pascal’s Pensées and read, 'I am the great silent spaces between wo
The evolutionists, piercing beneath the show of momentary stability, discovered, hidden in rudimentary organs, the discarded rubbish of the past. They detected the reptile under the lifted feathers of the bird, the lost terrestrial limbs dwindling beneath the blubber of the giant cetaceans. They saw life rushing outward from an unknown center, just as today the astronomer senses the galaxies fleeing into the infinity of darkness. As the spinning galactic clouds hurl stars and worlds across the night, so life, equally impelled by the centrifugal powers lurking in the germ cell, scatters the splintered radiance of consciousness and sends it prowling and contending through the thickets of the world.
It is a sad state of affairs that I donot know of any astronomer who fully understands the energy in their own daily environment. Untilthat changes, Dark Energy will always be a mystery to the astronomical community.
After a duration of a thousand years, the power of astrology broke down when, with Copernicus, Kepler, and Galileo, the progress of astronomy overthrew the false hypothesis upon which the entire structure rested, namely the geocentric system of the universe. The fact that the earth revolves in space intervened to upset the complicated play of planetary influences, and the silent stars, related to the unfathomable depths of the sky, no longer made their prophetic voices audible to mankind. Celestial mechanics and spectrum analysis finally robbed them of their mysterious prestige.
Earlier maps had underestimated the distances to other continents and exaggerated the outlines of individual nations. Now global dimensions could be set, with authority, by the celestial spheres. Indeed, King Louis XIV of France, confronted with a revised map of his domain based on accurate longitude measurements, reportedly complained that he was losing more territory to his astronomers than to his enemies.
I read not so long ago about the construction of a large telescope in Chile's Atacama Desert, where rainfall can average a millimetre a year and the air is fifty times as dry as the air in Death Valley. Needless to say, skies over the Atacama are pristine. The pilgrim astronomer ventures to the earth’s ravaged reaches in order to peer more keenly at other worlds, and I suppose the novelist is up to something similar.
We need science education to produce scientists, but we need it equally to create literacy in the public. Man has a fundamental urge to comprehend the world about him, and science gives today the only world picture which we can consider as valid. It gives an understanding of the inside of the atom and of the whole universe, or the peculiar properties of the chemical substances and of the manner in which genes duplicate in biology. An educated layman can, of course, not contribute to science, but can enjoy and participate in many scientific discoveries which as constantly made. Such participation was quite common in the 19th century, but has unhappily declined. Literacy in science will enrich a person's life.
The sciences are not sectarian. People do not persecute each other on account of disagreements in mathematics. Families are not divided about botany, and astronomy does not even tend to make a man hate his father and mother. It is what people do not know, that they persecute each other about. Science will bring, not a sword, but peace.
In high altitude astronomical facilities we routinely discharged large amounts of nitrogen gas into closed spaces. We were never informed by the astronomy management team about the abnormally low oxygen environments that the use of liquid nitrogen creates, how long term exposure to it manifests itself in human health and the resulting abnormal mental behaviors.
At the base of the immense pillar, tiny Babylon was in shadow. Then the darkness climbed the tower, like a canopy unfurling upward. It moved slowly enough that Hillalum felt he could count the moments passing, but then it grew faster as it approached, until it raced past them faster than he could blink, and they were in twilight... For the first time, he knew night for what it was: the shadow of the earth itself, cast against the sky.
If the Pentateuch is not inspired in its astronomy, geology, geography, history or philosophy, if it is not inspired concerning slavery, polygamy, war, law, religious or political liberty, or the rights of men, women and children, what is it inspired in, or about? The unity of God?—that was believed long before Moses was born. Special providence?—that has been the doctrine of ignorance in all ages. The rights of property?—theft was always a crime. The sacrifice of animals?—that was a custom thousands of years before a Jew existed. The sacredness of life?—there have always been laws against murder. The wickedness of perjury?—truthfulness has always been a virtue. The beauty of chastity?—the Pentateuch does not teach it. Thou shalt worship no other God?—that has been the burden of all religions.
Thus identified with astronomy, in proclaiming truths supposed to be hostile to Scripture, Geology has been denounced as the enemy of religion. The twin sisters of terrestrial and celestial physics have thus been joint-heirs of intolerance and persecution—unresisting victims in the crusade which ignorance and fanaticism are ever waging against science. When great truths are driven to make an appeal to reason, knowledge becomes criminal, and philosophers martyrs. Truth, however, like all moral powers, can neither be checked nor extinguished. When compressed, it but reacts the more. It crushes where it cannot expand—it burns where it is not allowed to shine. Human when originally divulged, it becomes divine when finally established. At first, the breath of a rage—at last it is the edict of a god. Endowed with such vital energy, astronomical truth has cut its way through the thick darkness of superstitious times, and, cheered by its conquests, Geology will find the same open path when it has triumphed over the less formidable obstacles of a civilized age.
There is talk of a new astrologer [Nicolaus Copernicus] who wants to prove that the earth moves and goes around instead of the sky, the sun, the moon, just as if somebody were moving in a carriage or ship might hold that he was sitting still and at rest while the earth and the trees walked and moved. But that is how things are nowadays: when a man wishes to be clever he must . . . invent something special, and the way he does it must needs be the best! The fool wants to turn the whole art of astronomy upside-down. However, as Holy Scripture tells us, so did Joshua bid the sun to stand still and not the earth.[Martin Luther stating his objection to heliocentrism due to his Scripture's geocentrism]
He had never been satisfied and never would be. It wasn't success he craved, or even fame, it was history: he wanted to crack the universe open like a ripe watermelon, to arrange the mess of pulpy seeds before his dumbfounded colleagues. He wanted to take the dripping red fruit in his hands and quantify the guts of infinity to look back into the dawn of time and glimpse the very beginning. He wanted to be remembered.
I'm confused. You make me confused. Just one glance at your eyes can mess up my whole world. My whole inner universe. The stars in my constellation are burning from the want to be in your eyes. They want to find the peace in those oceans. But you couldn't feel the burning light of my stars. You couldn't see the burning emotion of my body. So you walked away from my universe, leaving my lonely stars in the dark.
With increasing distance, our knowledge fades, and fades rapidly. Eventually, we reach the dim boundary—the utmost limits of our telescopes. There, we measure shadows, and we search among ghostly errors of measurement for landmarks that are scarcely more substantial. The search will continue. Not until the empirical resources are exhausted, need we pass on to the dreamy realms of speculation.
In very different ways, the possibility that the universe is teeming with life, and the opposite possibility that we are totally alone, are equally exciting. Either way, the urge to know more about the universe seems to me irresistible, and I cannot imagine that anybody of truly poetic sensibility could disagree.
For who could better describe the eye than God, Who made it? But as it is clearer than the day that God has left a good deal to our own efforts ... we should really follow in these things the thread of nature, by which first principles, reason and daily experience lead us. Therefore, He prompts the minds of great men to inquire into the nature which He created, and He furthers and conducts their studies. These things must be enough to us, and from Holy Scripture we should seek in the first place only those things which are necessary to salvation.
One of the most striking results of modern investigation has been the way in which several different and quite independent lines of evidence indicate that a very great event occurred about two thousand million years ago. The radio-active evidence for the age of meteorites; and the estimated time for the tidal evolution of the Moon's orbit (though this is much rougher), all agree in their testimony, and, what is far more important, the red-shift in the nebulae indicates that this date is fundamental, not merely in the history of our system, but in that of the material universe as a whole.
I think that the event which, more than anything else, led me to the search for ways of making more powerful radio telescopes, was the recognition, in 1952, that the intense source in the constellation of Cygnus was a distant galaxy—1000 million light years away. This discovery showed that some galaxies were capable of producing radio emission about a million times more intense than that from our own Galaxy or the Andromeda nebula, and the mechanisms responsible were quite unknown. ... [T]he possibilities were so exciting even in 1952 that my colleagues and I set about the task of designing instruments capable of extending the observations to weaker and weaker sources, and of exploring their internal structure.
His laws changed all of physics and astronomy. His laws made it possible to calculate the mass of the sun and planets. The way it's done is immensely beautiful. If you know the orbital period of any planet, say, Jupiter or the Earth and you know its distance to the Sun; you can calculate the mass of the Sun. Doesn't this sound like magic?We can carry this one step further - if you know the orbital period of one of Jupiter's bright moons, discovered by Galileo in 1609, and you know the distance between Jupiter and that moon, you can calculate the mass of Jupiter. Therefore, if you know the orbital period of the moon around the Earth (it's 27.32 days), and you know the mean distance between the Earth and the moon (it's about 200,039 miles), then you can calculate to a high degree of accuracy the mass of the Earth. … But Newton's laws reach far beyond our solar system. They dictate and explain the motion of stars, binary stars, star clusters, galaxies and even clusters of galaxies. And Newton's laws deserve credit for the 20th century discovery of what we call dark matter. His laws are beautiful. Breathtakingly simple and incredibly powerful at the same time. They explain so much and the range of phenomena they clarify is mind boggling. By bringing together the physics of motion, of interaction between objects and of planetary movements, Newton brought a new kind of order to astronomical measurements, showing how, what had been a jumble of confused observations made through the centuries were all interconnected.
When I saw how many people were objecting to the construction of the Thirty Meter Telescope atop Mauna Kea, I realized that there needed to be an open and honest discussion about the toxicity of the 13,796 feet very high altitude summit and the health and safety issues of astronomical observatories.
When I worked in high altitude astronomy, the worst sickness that I experienced was not at the 13,796 feet very high altitude summit of Mauna Kea Observatory (MKO) in Hawaii, it was at Kitt Peak National Observatory (KPNO) in Arizona at the much lower altitude of 6,875 feet. Due to my very high altitude experiences, I knew that this strange sickness was not primarily caused by altitude sickness and was most likely Sick Building Syndrome (SBS). After reporting various behavioral problems in all of the staff to the management team, my contract was not renewed, I was unable to legally protect the health and safety of the workers that I was responsible for, troubleshooting of this environmental problem stopped and I left in a sickened state for my next position before I could find the root cause.
When the National Optical Astronomy Observatory (NOAO) found out that Occupational Safety and Health Administration (OSHA) were going to visit the site to assist in bringing it into legal compliance, they freaked out! They insisted that the visit had to be canceled and the result was that I eventually became so sick from the toxic workplace environment that I had no option but to leave.
The biggest surprise that I had during my time in high altitude astronomy was being prevented from arranging a free Occupational Safety & Health Administration (OSHA) onsite evaluation to assist with bringing the observatory into OSHA compliance by the upper management team that I reported to.
I have been through the OSHA system twice and I can confirm that I did not have the right to a safe workplace or whistle-blower protection on either occasion.
The telescope, in enabling us to look far out into space, also allows us to look back in time. Light travels at about 186,000 miles per second. When we look up into the daylight sky, we are not seeing the sun as it currently is but as it was about eight minutes ago, since it takes that long for the light radiating from this familiar star to travel 93 million miles to Earth. Similarly, when the Giant Magellan Telescope (GMT) receives light waves from the depths of the universe, those waves will have originated from points as far as 76 sextillion (76,000,000,000,000,000,000,000) miles away. It will have taken those waves some 13 billion years to arrive on earth, meaning they left their source about a million years after the big bang, and roughly nine to ten billion years before Earth even formed.
The Earth is a very small stage in a vast cosmic arena. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot.
This success permits us to hope that after thirty or forty years of observation on the new Planet [Neptune], we may employ it, in its turn, for the discovery of the one following it in its order of distances from the Sun. Thus, at least, we should unhappily soon fall among bodies invisible by reason of their immense distance, but whose orbits might yet be traced in a succession of ages, with the greatest exactness, by the theory of Secular Inequal
Astronomy is, not without reason, regarded, by mankind, as the sublimest of the natural sciences. Its objects so frequently visible, and therefore familiar, being always remote and inaccessible, do not lose their dignity.
There is nothing particularly special about that location of the centre of mass. If you were to find yourself at the precise spot that is the centre of mass of the earth-moon system, the only thing unusual that you would notice is that there would be one thousand miles of rock on top of your head.Pluto is only about twice the size of Charon, so if you put Pluto and Charon on the cosmic seesaw you would find that the balance point is a little bit outside Pluto, rather than inside it. Again, there is nothing particularly special going on there. If you were to find yourself at that precise spot, you would only notice that you were very, very cold and could no longer breathe.
ASTRO-GYMNASTICSGo on a starlit night, stand on your head,leave your feet dangling outwards into space,and let the starry firmament you treadbe, for the moment, your elected base.Feel Earth's colossal weight of ice and granite,of molten magma, water, iron, and lead;and briefly hold this strangely solid planetbalanced upon your strangely solid head.
Before we invented civilization our ancestors lived mainly in the open out under the sky. Before we devised artificial lights and atmospheric pollution and modern forms of nocturnal entertainment we watched the stars. There were practical calendar reasons of course but there was more to it than that. Even today the most jaded city dweller can be unexpectedly moved upon encountering a clear night sky studded with thousands of twinkling stars. When it happens to me after all these years it still takes my breath away.
Surely it is a great thing to increase the numerous host of fixed stars previously visible to the unaided vision, adding countless more which have never before been seen, exposing these plainly to the eye in numbers ten times exceeding the old and familiar stars.
Algol is the name of the winking demon star, Medusa of the skies; fair but deadly to look on, even for one who is already dying.Ah, the bright stars of the night.Almost they obliterate the clear white pain. A thousand stars shining in the ether; but no dazzling newcomer. And so little time left, so little time...Yet still two-faced Medusa laughs from behind the clouds, demanding homage. Homage, Medusa, or a sword, a blade sharper than death itself.The wind stirs. Night clouds obscure the universe. A lower music now, a different kind of death.No stars tonight, my love.No Selene.
It doesnot matter; there’s many a heavenly body in the lot crowding upon us ofa night that mankind had never heard of, it being outside the sphereof its activities and of no earthly importance to anybody but to theastronomers who are paid to talk learnedly about its composition,weight, path--the irregularities of its conduct, the aberrations of itslight--a sort of scientific scandal-mongering.
How strange it was, I thought, that when the tiny though thousandfold beauties of the Earth disappeared and the immeasurable beauty of outer space rose in the distant quiet splendor of light, man and the greatest number of other creatures were supposed to be asleep! Was it because we were only permitted to catch a fleeting glimpse of those great bodies and then only in the mysterious time of a dream world, those great bodies about which man had only the slightest knowledge but perhaps one day would be permitted to examine more closely? Or was it permitted for the great majority of people to gaze at the starry firmament only in brief, sleepless moments so that the splendor wouldn't become mundane, so that the greatness wouldn't be diminished?
Consider now the Milky Way. Here also we see an innumerable dust, only the grains of this dust are no longer atoms but stars; these grains also move with great velocities, they act at a distance one upon another, but this action is so slight at great distances that their trajectories are rectilineal; nevertheless, from time to time, two of them may come near enough together to be deviated from their course, like a comet that passed too close to Jupiter. In a word, in the eyes of a giant, to whom our Suns were what our atoms are to us, the Milky Way would only look like a bubble of gas.
I had travelled from Spain into Morocco and from there south to the Atlas Mountains, at the edge of the Sahara Desert…one night, in a youth hostel that was more like a stable, I woke and walked out into a snowstorm. But it wasn’t the snow I was used to in Minnesota, or anywhere else I had been. Standing bare chest to cool night, wearing flip-flops and shorts, I let a storm of stars swirl around me. I remember no light pollution, heck, I remember no lights. But I remember the light around me-the sense of being lit by starlight- and that I could see the ground to which the stars seemed to be floating down. I saw the sky that night in three dimensions- the sky had depth, some stars seemingly close and some much farther away, the Milky Way so well defined it had what astronomers call “structure”, that sense of its twisting depths. I remember stars from one horizon to another, making a night sky so plush it still seems like a dream.It was a time in my life when I was every day experiencing something new. I felt open to everything, as though I was made of clay, and the world was imprinting on me its breathtaking beauty (and terrible reality.) Standing nearly naked under that Moroccan sky, skin against the air, the dark, the stars, the night pressed its impression, and my lifelong connection was sealed.
With my naked eye, on nights the moon climbs slowly, sometimes so dusted with rust and rose, brown, and gold tones that it nearly drips earth colors and seems intimately braided with Earth, it feels close, part of this world, a friend. But through the telescope, the moon seems- ironically- farther away…the gray-white moon in a sea of black, its surface in crisp relief, brighter than ever before. I am struck too, by the scene’s absolute silence.
In these countless stars, in their clusters and colors and constellations, in the “shooting” showers of blazing dust and ice, we have always found beauty. And in this beauty, the overwhelming size of the universe has seemed less ominous, earth’s own beauty more incredible. If indeed the numbers and distances of the night sky are so large that they become nearly meaningless, then let us find the meaning under our feet.
I compared what was really known about the stars with the account of creation as told in Genesis. I found that the writer of the inspired book had no knowledge of astronomy -- that he was as ignorant as a Choctaw chief -- as an Eskimo driver of dogs. Does any one imagine that the author of Genesis knew anything about the sun -- its size? that he was acquainted with Sirius, the North Star, with Capella, or that he knew anything of the clusters of stars so far away that their light, now visiting our eyes, has been traveling for two million years?If he had known these facts would he have said that Jehovah worked nearly six days to make this world, and only a part of the afternoon of the fourth day to make the sun and moon and all the stars?Yet millions of people insist that the writer of Genesis was inspired by the Creator of all worlds.Now, intelligent men, who are not frightened, whose brains have not been paralyzed by fear, know that the sacred story of creation was written by an ignorant savage. The story is inconsistent with all known facts, and every star shining in the heavens testifies that its author was an uninspired barbarian.I admit that this unknown writer was sincere, that he wrote what he believed to be true -- that he did the best he could. He did not claim to be inspired -- did not pretend that the story had been told to him by Jehovah. He simply stated the "facts" as he understood them.After I had learned a little about the stars I concluded that this writer, this "inspired" scribe, had been misled by myth and legend, and that he knew no more about creation than the average theologian of my day. In other words, that he knew absolutely nothing.And here, allow me to say that the ministers who are answering me are turning their guns in the wrong direction. These reverend gentlemen should attack the astronomers. They should malign and vilify Kepler, Copernicus, Newton, Herschel and Laplace. These men were the real destroyers of the sacred story. Then, after having disposed of them, they can wage a war against the stars, and against Jehovah himself for having furnished evidence against the truthfulness of his book.
My feeling is that an observer needs to see four hundred and fifty stars to get that feeling of infinitude, and be swept away…and I didn’t make that number up arbitrarily, that’s the number of stars that are available once you get dimmer than third magnitude. So in the city, you see a dozen stars, a handful, and it’s attractive to no one. And if there’s a hundred stars in the sky it still doesn’t do it. There’s a certain tipping point where people will look and there will be that planetarium view. And now you’re touching that ancient core, whether it’s collective memories or genetic memories, or something else form way back before we were even human…astronomer Bob Berman quoted in The End of Night
Above them, stars shine in constellations that Jenny recognizes from the ceiling of her father's house, the ones Mom and Dad helped her put up when she was in third grade. Constellations with names like Fire Truck and Ladybug Come Home, constellations that you won't find in any astronomer's catalogue.
In Anton Chekhov’s play the Three Sisters, sister Masha refuses ‘to live and not know why the cranes fly, why children are born, why the stars are in the sky. Either you know and you’re alive or it’s all nonsense, all dust in the wind.’ Why? Why? The striving to know is what frees us from the bonds of self, said Einstein. It’s the striving to know, rather than our knowledge-which is always tentative and partial- that is important. Instead of putting computers in our elementary schools, we should take the children out into nature, away from those virtual worlds in which they spend unconscionable hours, and let them see an eclipsed Moon rising in the east, a pink pearl. Let them stand in a morning dawn and watch a slip of a comet fling its trail around the Sun…Let the children know. Let them know that nothing, nothing will find in the virtual world of e-games, television, or the Internet matters half as much as a glitter of strs on an inky sky, drawing our attention into the incomprehensible mystery of why the universe is here at all, and why we are here to observe it. The winter Milky Way rises in the east, one trillion individually invisible points of light, one trillion revelations of the Ultimate Mystery, conferring on the watcher a dignity, a blessedness, that confounds the dull humdrum of the commonplace and opens a window to infinity.
I am a child of the Milky Way. The night is my mother. I am made of the dust of stars. Every atom in my body was forged in a star. When the universe exploded into being, already the bird longed for the wood and the fish for the pool. When the first galaxies fell into luminous clumps, already matter was struggling toward consciousness. The star clouds of Sagittarius are a burning bush. If there is a voice in Sagittarius, I’d be a fool not to listen. If God’s voice in the night is a scrawny cry, then I’ll prick up my ears. If night’s faint lights fail to knock me off my feet, then I’ll sit back on a dark hillside and wait and watch. A hint here and a trait there. Listening and watching. Waiting, always waiting, for the tingle in the spine.
The dangers that we face are part of the process, now well underway, of the unification of the planet--in language, culture, science, and commerce. They are both driven by the identical technological advances--this critical and delicate time coincides with the widespread availability of nuclear weapons. At the present rate of change, it seems likely that in the period between now and 2061, the turning point for the human species will have been reached.If we survive until then, our passage to the next apparition of Halley's Comet should be comparatively easy. That perihelion passage will be in March 2134, when the comet will make an unusually close encounter with the Earth. It will come as close as 0.09AU or 14 million kilometers, less than half the distance of the 1910 encounter. It will then be brighter than the brightest star. If there are those to do the commemorating, the years 2061 and 2134 should be celebrated for the courage, intelligence, and common purpose of a species forced by urgent necessity to come to its senses.
I find these comparisons particularly poignant: life versus death, hope versus fear. Space exploration and the highly mechanized destruction of people use similar technology and manufacturers, and similar human qualities of organization and daring. Can we not make the transition from automated aerospace killing to automated aerospace exploration of the solar system in which we live?
There are many arts and sciences of which a miner should not be ignorant. First there is Philosophy, that he may discern the origin, cause, and nature of subterranean things; for then he will be able to dig out the veins easily and advantageously, and to obtain more abundant results from his mining. Secondly there is Medicine, that he may be able to look after his diggers and other workman ... Thirdly follows astronomy, that he may know the divisions of the heavens and from them judge the directions of the veins. Fourthly, there is the science of Surveying that he may be able to estimate how deep a shaft should be sunk ... Fifthly, his knowledge of Arithmetical Science should be such that he may calculate the cost to be incurred in the machinery and the working of the mine. Sixthly, his learning must comprise Architecture, that he himself may construct the various machines and timber work required underground ... Next, he must have knowledge of Drawing, that he can draw plans of his machinery. Lastly, there is the Law, especially that dealing with metals, that he may claim his own rights, that he may undertake the duty of giving others his opinion on legal matters, that he may not take another man's property and so make trouble for himself, and that he may fulfil his obligations to others according to the law.
How quickly we grow accustomed to wonders. I am reminded of the Isaac Asimov story "Nightfall," about the planet where the stars were visible only once in a thousand years. So awesome was the sight that it drove people mad. We who can see the stars every night glance up casually at the cosmos and then quickly down again, searching for a Dairy Queen.
I’ve whittled my fascination with the cosmos down to this mantra: we can imagine the Universe as a giant void racing away from us at a frightening speed, or it could occur to us that, in fact, it is wrapped around us in all directions. Then, no matter where we are, we are at the centre of something wonderful. And that’s how I’ve always thought about it.
The cosmic perspective not only embraces our genetic kinship with all life on Earth but also values our chemical kinship with any yet-to-be discovered life in the universe, as well as our atomic kinship with the universe itself.
Mars One has the power to show people around the globe what is possible if we just all work on one goal. No human has left Earth’s orbit since 1972 and no one ever ploughed beyond the moon into deep space. It’s finally time to inspire the world and make the next giant leap for mankind.
What caused me to undertake the catalog was the nebula I discovered above the southern horn of Taurus on September 12, 1758, while observing the comet of that year. ... This nebula had such a resemblance to a comet in its form and brightness that I endeavored to find others, so that astronomers would not confuse these same nebulae with comets just beginning to shine. I observed further with suitable refractors for the discovery of comets, and this is the purpose I had in mind in compiling the catalog.After me, the celebrated Herschel published a catalog of 2000 which he has observed. This unveiling the sky, made with instruments of great aperture, does not help in the perusal of the sky for faint comets. Thus my object is different from his, and I need only nebulae visible in a telescope of two feet [focal length].
Let's grant that the stars are scattered through space, hither and yon. But how hither, and how yon? To the unaided eye the brightest stars are more than a hundred times brighter than the dimmest. So the dim ones are obviously a hundred times farther away from Earth, aren't they?Nope.That simple argument boldly assumes that all stars are intrinsically equally luminous, automatically making the near ones brighter than the far ones. Stars, however, come in a staggering range of luminosities, spanning ten orders of magnitude ten powers of ten. So the brightest stars are not necessarily the ones closest to Earth. In fact, most of the stars you see in the night sky are of the highly luminous variety, and they lie extraordinarily far away.If most of the stars we see are highly luminous, then surely those stars are common throughout the galaxy.Nope again.High-luminosity stars are the rarest. In any given volume of space, they're outnumbered by the low-luminosity stars a thousand to one. It's the prodigious energy output of high-luminosity stars that enables you to see them across such large volumes of space.
God is a pure mathematician!' declared British astronomer Sir James Jeans. The physical Universe does seem to be organised around elegant mathematical relationships. And one number above all others has exercised an enduring fascination for physicists: 137.0359991.... It is known as the fine-structure constant and is denoted by the Greek letter alpha (α).
[Regarding mathematics,] there are now few studies more generally recognized, for good reasons or bad, as profitable and praiseworthy. This may be true; indeed it is probable, since the sensational triumphs of Einstein, that stellar astronomy and atomic physics are the only sciences which stand higher in popular estimation.
It must have appeared almost as improbable to the earlier geologists, that the laws of earthquakes should one day throw light on the origin of mountains, as it must to the first astronomers, that the fall of an apple should assist in explaining the motions of the moon.
All we know for sure is that if some astronomer turned a telescope to a far-off star cluster tonight and found incontrovertible evidence of life, even microbial scavengers, it would be the most important discovery ever—proof that human beings are not so special after all. Except that we exist, too, and can understand and make such discoveries.
A few years after working on Mauna Kea, I discovered that I had radiation sickness

This is a love story about astronomy, he thought. Twin souls collide and love each other forever. And no one ever goes crazy. And no one ever dies. And the universe folds back on itself and clicks into place, and the pylons holding up the electrical wires are really trees. And the trees are really gods.
