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...

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!

If the Pentateuch is not inspired in its astronomy, geology, geography, history or philosophy, if it is not inspired concerning slavery, polygamy, war, law, religious or political liberty, or the rights of men, women and...

It seems impossible that you could get something from nothing, but the fact that once there was nothing and now there is a universe is evident proof that you can.

{Comment to Delambre on chemist Antoine Lavoisier’s execution during the French Revolution}Only a moment to cut off that head and a hundred years may not give us another like it.

Consider now the Milky Way. Here also we see an innumerable dust, only the grains of this dust are no longer atoms but stars; these grains also move with great velocities, they act at a...

At night the sky is pure astronomy.

My feeling is that an observer needs to see four hundred and fifty stars to get that feeling of infinitude, and be swept away…and I didn’t make that number up arbitrarily, that’s the number of...

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...

Cuando hablamos de la “ira” del cielo, la “agitación” del mar, la “resistencia” de los diamantes a ser tallados, la “atracción” que ejerce la Tierra sobre un asteroide cercano o la “excitación” de un átomo,...

For who could better describe the eye than God, Who made it? But as it is clearer than the day that God has left a good deal to our own efforts … we should really...

The discovery of a new dish does more for the happiness of the human race than the discovery of a star.

When you organize extraordinary missions, you attract people of extraordinary talent who might not have been inspired by or attracted to the goal of saving the world from cancer or hunger or pestilence.

We see it [the as-yet unseen, probable new planet, Neptune] as Columbus saw America from the coast of Spain. Its movements have been felt, trembling along the far-reaching line of our analysis with a certainty...

What has been done is little—scarcely a beginning; yet it is much in comparison with the total blank of a century past. And our knowledge will, we are easily persuaded, appear in turn the merest...

…and his analysis proved him to be the first of theoretical astronomers no less than the greatest of ‘arithmeticians.

I think that the event which, more than anything else, led me to the search for ways of making more powerful radio telescopes, was the recognition, in 1952, that the intense source in the constellation...

Majority of people find that nature is anything that walks and grows on planet Earth, astronomers have found that this nature stretches way beyond our atmosphere as far as we can see in to the...

The sciences are not sectarian. People do not persecute each other on account of disagreements in mathematics. Families are not divided about botany, and astronomy does not even tend to make a man hate his...

[In high school] my interests outside my academic work were debating, tennis, and to a lesser extent, acting. I became intensely interested in astronomy and devoured the popular works of astronomers such as Sir Arthur...

Thus identified with astronomy, in proclaiming truths supposed to be hostile to Scripture, Geology has been denounced as the enemy of religion. The twin sisters of terrestrial and celestial physics have thus been joint-heirs of...

We need science education to produce scientists, but we need it equally to create literacy in the public. Man has a fundamental urge to comprehend the world about him, and science gives today the only...

I believe that this Nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to earth.

[Asteroids are] the vermin of the skies.[Asteroids can block objects of interest on astronomical photographs.]
