1. “The discovery of a new dish does more for the happiness of the human race than the discovery of a star.” - Jean Anthelme Brillat-Savarin

2. “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.” - Elizabeth Redfern

3. “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.” - Galileo

4. “Recognize that the very molecules that make up your body, the atoms that construct the molecules, are traceable to the crucibles that were once the centers of high mass stars that exploded their chemically rich guts into the galaxy, enriching pristine gas clouds with the chemistry of life. So that we are all connected to each other biologically, to the earth chemically and to the rest of the universe atomically. That’s kinda cool! That makes me smile and I actually feel quite large at the end of that. It’s not that we are better than the universe, we are part of the universe. We are in the universe and the universe is in us.” - Neil deGrasse Tyson

5. “Stars are beautiful, but they must not take an active part in anything, they must just look on forever. It is a punishment put on them for something they did so long ago that no star now knows what it was.” - J.M. Barrie

6. “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.” - Ralph Waldo Emerson

7. “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.” - Neil deGrasse Tyson

8. “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.” - Auguste Villiers de l'Isle-Adam

9. “Your Excellency, I have no need of this hypothesis.” - Pierre Laplace

10. “Interviewer: Didn't Sagan want to believe?Druyan: he didn't want to believe. he wanted to know.” - Ann Druyan

11. “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.” - Gustave Flaubert

12. “For, to my mind, this is a certain principle, that nothing is here treated of but the visible form of the world. He who would learn astronomy, and other recondite arts, let him go elsewhere.(on commenting the text of Genesis 1:6)” - John Calvin

13. “who knows if the moon'sa balloon,coming out of a keen cityin the sky--filled with pretty people?( and if you and I shouldget into it,if theyshould take me and take you into their balloon,why thenwe'd go up higher with all the pretty peoplethan houses and steeples and clouds:go sailingaway and away sailing into a keen city which nobody's ever visited,wherealways it's Spring)and everyone'sin love and flowers pick themselves” - E.E. Cummings

14. “The church says the earth is flat; but I have seen its shadow on the moon, and I have more confidence even in a shadow than in the church.” - Ferdinand Magellan

15. “Two thousand years ago the night sky looked completely different, and so when you get right down to it, the Greek conceptions of star signs as related to birth dates are grossly inaccurate for today's day and age. It's called the Line of Procession: back then the sun didn't set in Taurus, but in Gemini. A September 24 birthday didn't mean you were a Libra, but a Virgo. And there was a thirteenth zodiac constellation, Ophiuchus the Serpent Bearer, which rose between Sagittarius and Scorpio for only four days.The reason it's all off kilter? The earth's axis wobbles. Life isn't nearly as stable as we want it to be.” - Jodi Picoult

16. “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.” - Mark Haddon

17. “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.” - Guillermo Gonzalez

18. “Attempts to locate oneself within history are as natural, and as absurd, as attempts to locate oneself within astronomy. On the day that I was born, 13 April 1949, nineteen senior Nazi officials were convicted at Nuremberg, including Hitler's former envoy to the Vatican, Baron Ernst von Weizsacker, who was found guilty of planning aggression against Czechoslovakia and committing atrocities against the Jewish people. On the same day, the State of Israel celebrated its first Passover seder and the United Nations, still meeting in those days at Flushing Meadow in Queens, voted to consider the Jewish state's application for membership. In Damascus, eleven newspapers were closed by the regime of General Hosni Zayim. In America, the National Committee on Alcoholism announced an upcoming 'A-Day' under the non-uplifting slogan: 'You can drink—help the alcoholic who can't.' ('Can't'?) The International Court of Justice at The Hague ruled in favor of Britain in the Corfu Channel dispute with Albania. At the UN, Soviet Foreign Minister Andrei Gromyko denounced the newly formed NATO alliance as a tool for aggression against the USSR. The rising Chinese Communists, under a man then known to Western readership as Mao Tze-Tung, announced a limited willingness to bargain with the still-existing Chinese government in a city then known to the outside world as 'Peiping.'All this was unknown to me as I nuzzled my mother's breast for the first time, and would certainly have happened in just the same way if I had not been born at all, or even conceived. One of the newspaper astrologists for that day addressed those whose birthday it was:There are powerful rays from the planet Mars, the war god, in your horoscope for your coming year, and this always means a chance to battle if you want to take it up. Try to avoid such disturbances where women relatives or friends are concerned, because the outlook for victory upon your part in such circumstances is rather dark. If you must fight, pick a man!Sage counsel no doubt, which I wish I had imbibed with that same maternal lactation, but impartially offered also to the many people born on that day who were also destined to die on it.” - Christopher Hitchens

19. “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.” - Pierre Simon de Laplace

20. “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.” - Carl Sagan

21. “Mathemata mathematicis scribuntur.” - Nicolaus Copernicus

22. “...Bana öyle geliyor ki, Pythagorasçılar bazılarının düşündüğü gibi, öğretilerini paylaşmaktan duydukları kıskançlıktan değil de, büyük insanlara ait böylesine güzel ve binbir zorlukla dolu keşif, maddî bir kazancı olmaksızın kalem oynatmayı sıkıcı bulan ya da başkalarının yüreklendirip örnek olmasıyla hür felsefe çalışmasına özendirilse de aklî donukluklarından ötürü filozoflar arasında tıpkı bal arılarının arasındaki erkek arılar gibi duran kişilerce hor görülmesin diye böyle yapıyordu.” - Nicolaus Copernicus

23. “Napoleon, when hearing about Laplace's latest book, said, 'M. Laplace, they tell me you have written this large book on the system of the universe, and have never even mentioned its creator.'Laplace responds, 'Je n'avais pas besoin de cette hypothèse-là. (I had no need of that hypothesis.)” - Pierre-Simon Laplace

24. “Astronomy to the selfish becomes astrology.” - Ralph Waldo Emerson

25. “Some piously record 'In the beginning God', but I say 'In the beginning hydrogen'.” - Harlow Shapley

26. “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.” - C. JoyBell C.

27. “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.” - H.G. Wells

28. “[The Old Astronomer to His Pupil]Reach me down my Tycho Brahe, I would know him when we meet,When I share my later science, sitting humbly at his feet;He may know the law of all things, yet be ignorant of howWe are working to completion, working on from then to now.Pray remember that I leave you all my theory complete,Lacking only certain data for your adding, as is meet,And remember men will scorn it, 'tis original and true,And the obloquy of newness may fall bitterly on you.But, my pupil, as my pupil you have learned the worth of scorn,You have laughed with me at pity, we have joyed to be forlorn,What for us are all distractions of men's fellowship and smiles;What for us the Goddess Pleasure with her meretricious smiles.You may tell that German College that their honor comes too late,But they must not waste repentance on the grizzly savant's fate.Though my soul may set in darkness, it will rise in perfect light;I have loved the stars too fondly to be fearful of the night.What, my boy, you are not weeping? You should save your eyes for sight;You will need them, mine observer, yet for many another night.I leave none but you, my pupil, unto whom my plans are known.You 'have none but me,' you murmur, and I 'leave you quite alone'?Well then, kiss me, -- since my mother left her blessing on my brow,There has been a something wanting in my nature until now;I can dimly comprehend it, -- that I might have been more kind,Might have cherished you more wisely, as the one I leave behind.I 'have never failed in kindness'? No, we lived too high for strife,--Calmest coldness was the error which has crept into our life;But your spirit is untainted, I can dedicate you stillTo the service of our science: you will further it? you will!There are certain calculations I should like to make with you,To be sure that your deductions will be logical and true;And remember, 'Patience, Patience,' is the watchword of a sage,Not to-day nor yet to-morrow can complete a perfect age.I have sown, like Tycho Brahe, that a greater man may reap;But if none should do my reaping, 'twill disturb me in my sleepSo be careful and be faithful, though, like me, you leave no name;See, my boy, that nothing turn you to the mere pursuit of fame.I must say Good-bye, my pupil, for I cannot longer speak;Draw the curtain back for Venus, ere my vision grows too weak:It is strange the pearly planet should look red as fiery Mars,--God will mercifully guide me on my way amongst the stars.” - Sarah Williams

29. “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.” - Mike Brown

30. “The lifetime of a human being is measured by decades, the lifetime of the Sun is a hundred million times longer. Compared to a star, we are like mayflies, fleeting ephemeral creatures who live out their lives in the course of a single day.” - Carl Sagan

31. “When we look up at night and view the stars, everything we see is shinning because of distant nuclear fusion.” - Carl Sagan

32. “It's amazing to me that we humans have the intellectual capacity to ask deep questions and to devise methods for learning how the universe works and how its contents evolve with time.” - Alex Filippenko

33. “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.” - Carl Sagan

34. “My dear Kepler, what would you say of the learned here, who, replete with the pertinacity of the asp, have steadfastly refused to cast a glance through the telescope? What shall we make of this? Shall we laugh, or shall we cry?” - Galileo Galilei

35. “At every level in our inventory, nothing seems special about our Earth, our Sun, our Galaxy, our Local Group. Evidently, mediocrity reigns throughout. Such is our niche in the Universe.” - Eric Chaisson

36. “... the blast signatures of a detonated supernova and that of a nuclear bomb are identical.” - Eric Chaisson

37. “At night the sky is pure astronomy.” - Nicole Krauss

38. “Bien que les étoiles ne parlent pas, même en étant silencieux, ils crient.Although the stars do not speak, even in being silent they cry out.” - Jean Calvin

39. “Our existence in this place, this microscopic corner of the cosmos, is fleeting. With utter disregard for our wants and needs, nature plays out its grand acts on scales of space and time that are truly hard to grasp. Perhaps all we can look to for real solace is our endless capacity to ask questions and seek answers about the place we find ourselves in.” - Caleb Scharf

40. “Each star had cost an effort. For each there had been planning, watching and anticipation. Each one recalled to me a place, a time, a season. Each one now has a personality. The stars, in short, had become my stars.” - Leslie C. Peltier

41. “The great radio telescopes of the world are constructed in remote locations for the same reason Paul Gauguin sailed to Tahiti: For them to work well they must be far from civilization.” - Sagan, Carl

42. “We, all of us, are what happens when a primordial mixture of hydrogen and helium evolves for so long that it begins to ask where it came from.” - Jill Tarter

43. “Implicitly or explicitly, the rhythms of our lives, the movement from season to season, the patterns of the winds, and the pulse of the tides all depend on the apparent motions of the sun and moon and stars. Yet most modern urban dwellers are only dimly aware of the night sky ― the stars and their myriad forms. They are only slightly more aware of the phases of the moon or the motions of the sun. Even those who take the daily horoscope seriously generally have a very poor notion of its connection with astronomical phenomena.” - Ray A. Williamson

44. “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.” - Ted Chiang

45. “A circle has no end.” - Isaac Asimov

46. “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.” - Anaximander of Miletus

47. “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.” - Brad Leithauser

48. “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.” - Chet Raymo

49. “Unlike what you may be told in other sectors of life, when observing the universe, size does matter, which often leads to polite ‘telescope envy’ at gatherings of amateur astronomers.” - Neil deGrasse Tyson

50. “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.” - Richard Dawkins
