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...

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

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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....

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...

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...

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...

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...

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...

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

Did you know that the center of a Protostar (the star in the middle of a nebula) is called a Nuclear Furnace? So you can call that the star’s “heart.” The heart of a star...

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...

… the irregularities of the motion of Uranus…in order to find out whether they may be attributed to the action of an undiscovered planet beyond it.[John Couch Adams on how he began to discover Neptune.]

We are probably nearing the limit of all we can know about astronomy.

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...

The motivation is either an interest in space, astronomy, science fiction or being at one with the universe. Some see it as a spiritual choice.

The effect of a concept-driven revolution is to explain old things in new ways. The effect of a tool-driven revolution is to discover new things that have to be explained.

In the year 1456 … a Comet was seen passing Retrograde between the Earth and the sun… Hence I dare venture to foretell, that it will return again in the year 1758.

Some people think emotionally more often than they think politically. Some think politically more often than they think rationally. Others never think rationally about anything at all.No judgment implied. Just an observation.

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...
