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...

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...

When I die, I will return to where I first came from. Back to the stars.

A hundred years ago, Auguste Comte, … a great philosopher, said that humans will never be able to visit the stars, that we will never know what stars are made out of, that that’s the...

Don’t STOP until you reach the TOP. When you reach the TOP don’t STOP keep moving UP

Your Excellency, I have no need of this hypothesis.

Una científica compañera mía me contaba un reciente viaje que realizó a la meseta de Nueva Guinea, donde visitó una tribu todavía en la edad de piedra que apenas había tenido contactos con la civilización....

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...

We tell them about Earth science, astronomy, plant science and marine science. But what we don’t do is explain what the four basic sciences are and what the building blocks are. We go too broad...

I look forward to the day when the solar system becomes our collective backyard—explored not only with robots, but with the mind, body, and soul of our species.

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...

Across the sea of space, the stars are other suns.

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.

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...

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...

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...

Timing is easy to predict through the movement of the stars as they give the propensity of pure potential.

Any patch of sunlight in a wood will show you something about the sun which you could never get from reading books on astronomy. These pure and spontaneous pleasures are ‘patches of Godlight’ in the...

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...

Herschel removed the speckled tent-roof from the world and exposed the immeasurable deeps of space, dim-flecked with fleets of colossal suns sailing their billion-leagued remoteness.

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...

I esteem myself happy to have as great an ally as you in my search for truth. I will read your work … all the more willingly because I have for many years been a...

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...

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.

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...

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.

Light brings us the news of the Universe.

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...

Though we might like to think so, humankind is not at any special, unique or privileged location in the gargantuan, perhaps infinite, Universe.

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...

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...

Orion is above the horizon now, and near it Jupiter, brighter than it will ever be … But i expect you can see it too. Some of our stars are the same.

Who will venture to place the authority of Copernicus above that of the Holy Spirit?[Lutheran theologian Abraham Calovius illustrating his objection to heliocentrism due to the Bible’s support of geocentrism]

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...

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...

The more important fundamental laws and facts of physical science have all been discovered, and these are now so firmly established that the possibility of their ever being supplanted in consequence of new discoveries is...

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...

As a rule, theologians know nothing of this world, and far less of the next; but they have the power of stating the most absurd propositions with faces solemn as stupidity touched by fear.It is...

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...

A time will come when men will stretch out their eyes. They should see planets like our Earth.

An attempt to study the evolution of living organisms without reference to cytology would be as futile as an account of stellar evolution which ignored spectroscopy.

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 phenomena of nature, especially those that fall under the inspection of the astronomer, are to be viewed, not only with the usual attention to facts as they occur, but with the eye of reason...

By looking far out into space we are also looking far back into time, back toward the horizon of the universe, back toward the epoch of the Big Bang.

This century will be called Darwin’s century. He was one of the greatest men who ever touched this globe. He has explained more of the phenomena of life than all of the religious teachers. Write...

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...

Le Verrier—without leaving his study, without even looking at the sky—had found the unknown planet [Neptune] solely by mathematical calculation, and, as it were, touched it with the tip of his pen!
