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...

Full spectrum lights should be used in all daytime offices for good health.

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 history of the astronomy of the nineteenth century will be incomplete without a catalogue of his labours. He was one of the founders of the Astronomical Society, and his attention to its affairs was as accurate and minute as if it had been a firm of which he was the chief clerk, with expectation...

[They] pervert the course of nature [by saying] the sun does not move and that it is the earth that revolves and that it turns.[John Calvin illustrating his opposition to heliocentrism in a sermon due to the Bible’s support of geocentrism]

In the beginning of the year 1665 I found the Method of approximating series & the Rule for reducing any dignity of any Binomial into such a series. The same year in May I found the method of Tangents of Gregory & Slusius, & in November had the direct method of fluxions & the next...

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...

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...

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...

Maybe you who condemn me are in greater fear than I who am condemned.

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...

[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...

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.

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 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...

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...

There are reasons to doubt that what we call the laws of physics necessarily apply everywhere in the universe—or that they were applicable to every time in its history.

I have looked further into space than ever human being did before me. I have observed stars of which the light, it can be proved, must take two million years to reach the earth.[Having identified Uranus (1781), the first planet discovered since antiquity.]

unreal.” We have yet to prove that word.

Science is the one human activity that is truly progressive. The body of positive knowledge is transmitted from generation to generation.

When he came to me wanting to do something in astronomy, I got excited. Astronomy is my first love in science. But he wanted to buy a big telescope which we couldn’t afford.

Kepler’s laws, although not rigidly true, are sufficiently near to the truth to have led to the discovery of the law of attraction of the bodies of the solar system. The deviation from complete accuracy is due to the facts, that the planets are not of inappreciable mass, that, in consequence, they disturb each other’s...

Astronomy has always been a fascination of mine.

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...

In the past, men had projected their feminine qualities of emotions, nurturance, and sensitivity onto women. With the recent activation of the feminine centers represented by the asteroids, men have been pressured and encouraged to both “own: and develop these qualities.

The wreckage of stars – I built a world from this wreckage.

The more of us that feel the universe, the better off we will be in this world.

And when statesmen or others worry him [the scientist] too much, then he should leave with his possessions. With a firm and steadfast mind one should hold under all conditions, that everywhere the earth is below and the sky above and to the energetic man, every region is his fatherland.

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.

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...

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...

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.

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,...

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...

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.

The history of astronomy is a history of receding horizons.

…look up and see the madnessorganized in the stars.

Io, Europa, Ganimedes puer, atque Calistolascivo nimium perplacuere Iovi.(Io, Europa, the boy Ganymede, and Callisto greatly pleased lustful Jupiter.)[Marius naming Jupiter’s moons]

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...

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.

[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...

This sight… is by far the noblest astronomy affords.

Science, enabled by engineering, empowered by NASA, tells us not only that we are in the universe but that the universe is in us. And for me, that sense of belonging elevates, not denigrates, the ego.

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 excellent health and a good skin color, I recommend that people sit next to a shady ultraviolet transmitting window when indoors.

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...

A circle has no end.

Our universe grants every soul a twin-a reflection of themselves -the kindred spirit – And no matter where they are or how far away they are from each other- even if they are in different dimensions, they will always find one another. This is destiny; this is love.

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...

Astronomy teaches the correct use of the sun and the planets.
