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.

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...

When we look up at night and view the stars, everything we see is shinning because of distant nuclear fusion.

Philosophy [nature] is written in that great book which ever is before our eyes — I mean the universe — but we cannot understand it if we do not first learn the language and grasp...

Just don’t be surprised if while you are looking to the heavens, I am looking to you. You, my dear Mrs. Hastings,are all the beauty, guidance, and light I will ever need.

Discover the force of the skies O Men: once recognised it can be put to use.

I thought to myself: if it’s true that every person has a star in the sky, mine must be distant, dim, and absurd. Perhaps I never had a star.

Aristotle’s opinion… that comets were nothing else than sublunary vapors or airy meteors… prevailed so far amongst the Greeks, that this sublimest part of astronomy lay altogether neglected; since none could think it worthwhile to...

Earlier maps had underestimated the distances to other continents and exaggerated the outlines of individual nations. Now global dimensions could be set, with authority, by the celestial spheres. Indeed, King Louis XIV of France, confronted...

In the progressive growth of astronomy, physics or mechanical science was developed, and when this had been, to a certain degree, successfully cultivated, it gave birth to the science of chemistry.

Love is only one fine star away.

In my opinion the separation of the c- and ac-stars is the most important advancement in stellar classification since the trials by Vogel and Secchi … To neglect the c-properties in classifying stellar spectra, I...

I have realized; it is during the times I am far outside my element that I experience myself the most. That I see and feel who I really am, the most! I think that’s what...

The optimization of cosmic darkness and of Earth’s location within the dark universe that sacrifices neither the material needs of human beings nor their capacity to gain knowledge about the universe reflects masterful engineering at...

[Regarding mathematics,] there are now few studies more generally recognized, for good reasons or bad, as profitable and praiseworthy. This may be true; indeed it is probable, since the sensational triumphs of Einstein, that stellar...

Science literacy is being plugged into the forces that power the universe. There is no excuse for thinking that the Sun, which is a million times the size of Earth, orbits Earth.

His laws changed all of physics and astronomy. His laws made it possible to calculate the mass of the sun and planets. The way it’s done is immensely beautiful. If you know the orbital period...

Staring at the blue sky causes insomnia to occur in the human.

The others would then fall silent and she would continue about doped gallium arsenide detectors, or the ethanol content of the galactic cloud W-3. The quantity of 200-proof alcohol in this single interstellar cloud was...

Surely it is a great thing to increase the numerous host of fixed stars previously visible to the unaided vision, adding countless more which have never before been seen, exposing these plainly to the eye...

Then they wondered if there were men in the stars. Why not? And as creation is harmonious, the inhabitants of Sirius ought to be huge, those of Mars middle-sized, those of Venus very small. Unless...

If there is anything that can bind the mind of man to this dreary exile of our earthly home and can reconcile us with our fate so that one can enjoy living,—then it is verily...

The evening starIs the mostbeautifulof all stars

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...
