Astronomical Observations Quotes

People give ear to an upstart astrologer who strove to show that the earth revolves, not the heavens of the firmament, the sun and the moon. This fool wishes to reverse the entire scheme of astronomy; but sacred Scripture tells us that Joshua commanded the sun to stand still, not the earth

When I grew up as a kid, we didn't know there were any other planets outside of our own solar system. It was widely speculated that planet formation was an incredibly rare event and that it's possible that other planets just don't exist in our galaxy, and it's just this special situation where we happen to have planets around our sun.

Accordingly, since nothing prevents the earth from moving, I suggest that we should now consider also whether several motions suit it, so that it can be regarded as one of the planets. For, it is not the center of all the revolutions.

Galileo - the father of modern physics - indeed of modern science.

Astronomy is one of the sublimest fields of human investigation. The mind that grasps its facts and principles receives something of the enlargement and grandeur belonging to the science itself. It is a quickener of devotion.

And yet it moves.

Finally we shall place the Sun himself at the center of the Universe.

We've been surrounded by images of space our whole lives, from the speculative images of science fiction to the inspirational visions of artists to the increasingly beautiful pictures made possible by complex technologies. But whilst we have an overwhelmingly vivid visual understanding of space, we have no sense of what space sounds like.

Among the authorities it is generally agreed that the Earth is at rest in the middle of the universe, and they regard it as inconceivable and even ridiculous to hold the opposite opinion. However, if we consider it more closely the question will be seen to be still unsettled, and so decidedly not to be despised. For every apparent change in respect of position is due to motion of the object observed, or of the observer, or indeed to an unequal change of both.

Galileo had already made a significant beginning toward a knowledge of the law of motion. He discovered the law of inertia and the law of bodies falling freely in the gravitational field of the earth.

Note to academics: Aristarchus' track record of astronomical research would probably have guaranteed him tenure somewhere, if tenure had been invented. His stack of reprints included measuring the distances of the Moon and Sun.

I got interested in astronomy at the age of 8 because I was looking at an atlas of the planets in my parents' apartment in Arlington, where I grew up. I got a telescope at age 10, which is pretty normal, and by the time I was in eighth grade, I had already seen a lot of cheesy sci-fi films.

So far as hypotheses are concerned, let no one expect anything certain from astronomy, which cannot furnish it, lest he accept as the truth ideas conceived for another purpose, and depart from this study a greater fool than when he entered it.

Mars is essentially in the same orbit. Mars is somewhat the same distance from the Sun, which is very important. We have seen pictures where there are canals, we believe, and water.

Astronomy is ... the only progressive Science which the ancient world produced.

One of the things that was kind of shocking for humans... was to come to terms with was the fact that, hey, we may not be the center of the universe.

I actually believe more in outer space in Virginia, because I can look up at the sky and count the stars.

Galileo, perhaps more than any other single person, was responsible for the birth of modern science.

Common sense is that which tells us the world is flat.

An astrolabe is relatively unknown in today's world. But, at the time, in the 13th century, it was the gadget of the day. It was the world's first popular computer. And it was a device that, in fact, is a model of the sky.

The Egyptians saw the sun and called him Ra, the Sun God. He rode across the sky in his chariot until it was time to sleep. Copernicus and Galileo proved otherwise, and poor Ra lost his divinity.

Hubble is unique. Nothing else can do what it can do. Once it's gone, we're going to be paralyzed.

It was not just the Church that resisted the heliocentrism of Copernicus.

The exploration of space: Be it by humans or robots, based on the best choice for the mission and the most efficient means to return the data and science sought. Most of the time, this will mean we send robots due to cost and danger. But sometimes, we will need the irreplaceable judgment and descriptive abilities of a person on the spot.

For many centuries, humans have speculated that there might be planetary systems around other stars and that there could be extraterrestrial life there and even intelligent being. However, those were simply speculations, and now we have evidence for the first part of these ideas.
