53 Astronomy Quotes

As an astronomer in the true sense of the term, Sir John Herschel stood before all his contemporaries. Nay, he stood almost alone.

We are star stuff which has taken its destiny into its own hands. The loom of time and space works the most astonishing transformations of matter.

Make then your forecasts, my lords Astrologers, with your slavish physicians, by means of those astrolabes with which you seek to discern the fantastic nine moving spheres; in these you finally imprison your own minds, so that you appear to me but as parrots in a cage, while I watch you dancing up and down, turning and hopping within those circles.

This universe, which is the same for all, has not been made by any god or man, but it always has been, is, and will be an ever-living fire, kindling itself by regular measures and going out by regular measures.

The motion of the stars over our heads is as much an illusion as that of the cows, trees and churches that flash past the windows of our train.

For when a ship is floating calmly along, the sailors see its motion mirrored in everything outside, while on the other hand they suppose that they are stationary, together with everything on board. In the same way, the motion of the earth can unquestionably produce the impression that the entire universe is rotating.

Hence I feel no shame in asserting that this whole region engirdled by the moon, and the center of the earth, traverse this grand circle amid the rest of the planets in an annual revolution around the sun. Near the sun is the center of the universe. Moreover, since the sun remains stationary, whatever appears as a motion of the sun is really due rather to the motion of the earth.

When twenty years of the Moon's reign have passed another will take up his reign for seven thousand years. When the exhausted Sun takes up his cycle then my prophecy and threats will be accomplished.

Our sun is one of 100 billion stars in our galaxy. Our galaxy is one of billions of galaxies populating the universe. It would be the height of presumption to think that we are the only living things in that enormous immensity.

Astronomy is perhaps the science whose discoveries owe least to chance, in which human understanding appears in its whole magnitude, and through which man can best learn how small he is.

The next question was - what makes planets go around the sun? At the time of Kepler some people answered this problem by saying that there were angels behind them beating their wings and pushing the planets around an orbit. As you will see, the answer is not very far from the truth. The only difference is that the angels sit in a different direction and their wings push inward.

There are 1011 stars in the galaxy. That used to be a huge number. But it's only a hundred billion. It's less than the national deficit! We used to call them astronomical numbers. Now we should call them economical numbers.

Finally we shall place the Sun himself at the center of the Universe. All this is suggested by the systematic procession of events and the harmony of the whole Universe, if only we face the facts, as they say, 'with both eyes open.'

At rest, however, in the middle of everything is the sun. For, in this most beautiful temple, who would place this lamp in another or better position than that from which it can light up the whole thing at the same time? For, the sun is not inappropriately called by some people the lantern of the universe, its mind by others, and its ruler by still others. The Thrice Greatest labels it a visible god, and Sophocles' Electra, the all-seeing. Thus indeed, as though seated on a royal throne, the sun governs the family of planets revolving around it.

Therefore alongside the ancient hypotheses, which are no more probable, let us permit these new hypotheses also to become known, especially since they are admirable as well as simple and bring with them a huge treasure of very skillful observations. So far as hypotheses are concerned, let no one expect anything certain from astronomy, which cannot furnish it, lest he accept as the truth ideas conceived for another purpose, and depart from this study a greater fool than when he entered it.

What are the stars but points in the body of God where we insert the healing needles of our terror and longing?

It is then unnecessary to investigate whether there be beyond the heaven Space, Void or Time. For there is a single general space, a single vast immensity which we may freely call Void; in it are innumerable globes like this one on which we live and grow. This space we declare to be infinite, since neither reason, convenience, possibility, sense-perception nor nature assign to it a limit. In it are an infinity of worlds of the same kind as our own.

Are we assured that there are two things which lead men to believe in the Gods, as we have already stated? What are they? One is the argument about the soul, which has been already mentioned - that it is the eldest and most divine of all things, to which motion attaining generation gives perpetual existence; the other was an argument from the order of the motion of the stars, and of all things under the dominion of the mind which ordered the universe. If a man look upon the world not lightly or ignorantly, there was never any one so godless who did not experience an effect opposite to that which the many imagine. For they think that those who handle these matters by the help of astronomy, and the accompanying arts of demonstration, may become godless, because they see, as far as they can see, things happening by necessity, and not by an intelligent will accomplishing good.

The priests had been told that I had dared to say that the moon was the world I came from and that their world was only a moon. They believed that constituted an adequately just pretext to condemn me to drowning, which was their way of exterminating atheists.

Hoyle: A star is basically a pretty simple object. Voice from Audience: You'd look pretty simple too, Fred, from a distance of ten parsecs.

To a body of infinite size there can be ascribed neither centre nor boundary... Thus the Earth no more than any other world is at the centre.

Bruno - one of the greatest and bravest of men - greatest of all martyrs - perished at the stake, because he insisted on the existence of other worlds and taught the astronomy of Galileo...

The Thing of the idols, the green, sticky spawn of the stars, had awaked to claim his own. The stars were right again, and what an age-old cult had failed to do by design, a band of innocent sailors had done by accident. After vigintillions of years great Cthulhu was loose again, and ravening for delight.

It is as though a star throws the whole secret history of its being into its spectrum, and we have only to learn how to read it aright in order to solve the most abstruse problems of the physical Universe.

What parts of the interior or the atmosphere give rise to the various phenomena, or indeed, if these regions have any parts at all, are questions which we ask of the stars in vain.

'Under the old dispensation, before the advent of science, when this little world was all, and the sun, moon, and stars were merely fixtures overhead to give light and warmth, the conception of a being adequate to create and control it all was easier. The storms were expressive of his displeasure, the heavens were his throne, and the earth was his footstool. But in the light of modern astronomy one finds himself looking in vain for the God of his fathers, the magnified man who ruled the ancient world. In his place we have an infinite and eternal Power whose expression is the visible universe, and to whom man is no more and no less than any other creature.

An air of mystery surrounds his researches, lying, as they do, chiefly in depths to which the far-seeing eye of the telescope alone penetrates.

I've been saying for a long time that I'm hoping to find intelligent life in Washington ... I'm reasonably sure there must be life in this solar system, on Mars or on Europa, and other places. I think life is probably going to be ubiquitous, though we still don't have any proof of that yet - and still less, any proof of intelligent life anywhere. But I hope that will be coming in the next decade or so through radio astronomy or, perhaps, the discovery of objects in space which are obviously artificial. Astronomical engineering - that may be the other thing to look for.

To obtain a mental picture of the distance to the nearest star, compared to the nearest planet, you must imagine a world in which the closest object to you is only five feet away - and there is nothing else to see until you have travelled a thousand miles.

One of the English science-fiction writers once said, 'Sometimes I think we're alone in the universe, and sometimes I think we're not. In either case the idea is quite staggering.' ... I must say I agree with him.

I have always read that the world, both land and water, was spherical, as the authority and researches of Ptolemy and all the others who have written on this subject demonstrate and prove, as do the eclipses of the moon and other experiments that are made from east to west, and the elevation of the North Star from north to south.

'Look, here are we on this starry night staring into space, and I must say I feel as small as dust lying down here'

Note, accordingly, how little it means to say something like 'Uranus moves into Aquarius'. Aquarius is a miscellaneous set of stars all at different distances from us, which have no connection with each other except that they constitute a (meaningless) pattern when seen from a certain (not particularly special) place in the galaxy (here). A constellation is not an entity at all, not the kind of thing that Uranus, or anything else, can sensibly be said to 'move into'.

The shape of a constellation, moreover, is ephemeral. A million years ago our Homo erectus ancestors gazed out nightly at a set of very different constellations. A million years hence, our descendants will see yet other shapes in the sky, and their astrologer (if our species has not grown up and sent them packing long since) will be fabricating their oracles on the basis of a different zodiac.

It now remains that we find the amount of time of descent through the channel. This we shall obtain from the marvelous property of the pendulum, which is that it makes all its vibrations, large or small, in equal times. This requires, once and for all, that two or three or four patient and curious friends, having noted a fixed star that stands against some fixed marker, taking a pendulum of any length, shall go counting its vibrations during the whole time of return of the fixed star to its original point, and this will be the number of vibrations in 24 hours. From the number of these we can find the number of vibrations of any other pendulums, longer or shorter, at will, so that if for example those counted by us in 24 hours were 234,567, then taking another shorter pendulum with which one counts 800 vibrations while another counts 150 of the longer pendulum, we already have, by the golden rule, the number of vibrations for the whole time of 24 hours; and if we want to know the time of descent through the channel, we can easily find not only the minutes, seconds, and sixtieths of seconds, but beyond that as we please. It is true that we can pass a more exact measure by having observed the flow of water through a thin passage, for by collecting this and having weighed what passes in one minute, for example, then by weighing what passes in the time of descent through the channel we can find the most exact measure and quantity of this time, especially by making use of a balance so precise as to weigh one sixtieth of a grain.
