Quotes About Astronomy

I wonder why it's orange," I mused aloud. To my surprise, I heard Emily answer. "When the moon is low in the sky, the light scatters because it has to pass through more layers of the atmosphere than when it's overhead. By the time the light reaches our eyes, the blue, green, and purple parts of the spectrum have scattered, leaving only yellow, orange, and red visible to us." "How do you know that?" I marveled, turning to her.

At night the sky is pure astronomy.

That night, stargazing on the deck with Dad, eyes on the sky, he pointed out Orion, Betelgeuse. It's an art to read the stars, baby. I never wanted to leave his side-my sure song for so long. Now? His eyes are stone changed. Just looking at them hurts my heart.

former atheist and astronomer Alan Sandage, said, "As I said before, the world is too complicated in all of its parts to be due to chance alone. I am convinced that the existence of life with all its order in each of its organisms is simply too well put together. . . . The more one learns of biochemistry the more unbelievable it becomes unless there is some kind of organizing principle—an architect for believers.

U—The Universe Is Expanding

These two Bell Lab scientists had discovered the afterglow from the Big Bang fireball explosion!

Technically known as the cosmic background radiation

Edwin Hubble looked through his telescope more than a decade later that scientists finally confirmed that the universe is expanding and that it's expanding from a single point.

There's a planet out there somewhere. Fairly close, I'd guess. A freewheeling planet, not tied to any sun, although I gather that it could insert itself into a solar system any time it wishes." "That would take some doing. It would mess up the orbits of all the other planets." "Not necessarily," said Maxwell. "It wouldn't have to take an orbit in the same plane as the other planets. That would hold down the effect of its being there.

Em Samarcanda, dois séculos antes da invenção do telescópio, Ulug Beg registava a trajetória de mil e dezoito estrelas e recalculava o ano estelar com uma diferença de segundos em relação aos resultados obtidos atualmente pela eletrónica.

the dewy night unrolls a heaven thickly jewelled with sparkling stars

The Greeks shape bronze statues so real they seem to breathe, And carve cold marble until it almost comes to life. The Greeks compose great orations, and measure The heavens so well they can predict the rising of the stars. But you, Romans, remember your great arts; To govern the peoples with authority, To establish peace under the rule of law, To conquer the mighty, and show them mercy once they are conquered. -Virgil, Aeneid VI, 847-853

I reflect now that the earth is only a pebble flicked off accidentally from the face of the sun and that there is no life anywhere in the abysses of space.

Time on Hubble is a precious commodity. Astronomers across the world regularly ask for much more time than is available. Keeping Hubble working 24/7 is no small task. Not a single second must be lost and all tasks — either observations or so-called 'housekeeping' tasks, such as repositioning of the telescope, or uploading new observing schedules — are meticulously planned.

But Mesquita found Andrés de San Martín, the esteemed astronomer-astrologer; Hernando Morales

The universe doesn't respect the boundaries between different disciplines. The differences between biology and astronomy and chemistry and so on, these are man-made artifacts of thinking. I think the whole system is doomed unless one decides that all these barriers are cleared.

the Maya knew the time taken by the moon to orbit the earth. Their estimate of this period was 29.528395 days – extremely close to the true figure of 29.530588 days computed by the finest modern methods.11 The Mayan priests also had in their possession very accurate tables for the prediction of solar and lunar eclipses and were aware that these could occur only within plus or minus eighteen days of the node (when the moon's path crosses the apparent path of the sun).

The atheist says we live in a random universe, he has no right to rely on inductive inference, he has no reason to expect causality, or simply the uniformity of nature. He has no basis for believing in the uniformity of nature, but if he has no basis for the uniformity of nature he has no basis for doing science, it's gone, kaput. Biology, chemistry, astronomy, psychology, history, grammar, all of it is gone, there are no sciences without inductive inference

Roman history is like astronomy in that respect. New experiments cannot be carried out. But a vast mass of distant and ancient phenomena can be observed through tiny packets of residual data, and the forces and cataclysmic events that formed the observable universe can be reconstructed.

The proper term is "occultation." The moon occults the sun, casting a small shadow onto the surface of the earth. It is not a solar eclipse, but in fact an eclipse of the earth.

The term "solar eclipse" is in fact a misnomer. An eclipse occurs when one object passes into a shadow cast by another. In a solar eclipse, the moon does not pass into the sun's shadow, but instead passes between the sun and the earth, obscuring the sun—

In reasonably simple form, galactic orbits can be treated like the orbits of planets around a sun, with one exception: the central gravity source is not a point, but a disk with thickness in three dimensions.
