Quotes About Astronomy

Black holes are enigmatic astronomical objects, areas where the gravity is so immense that it has warped spacetime so that not even light can escape.

Well, listen, I want to talk to Rynald a bit more-" "About astronomy? Maybe he'll show you his telescope,

Oh, I love astronomy. I'm a Pisces. What sign are you?" Which had made Mac laugh again, and he started to explain the difference between astronomy and astrology. Tiffany was apparently absolutely fascinated…and fascinating. His gaze--and Jason's--was riveted on her. I gave another little shrug, feeling a need to defend my sister, who might be in need of a trip down the yellow brick road to ask the wizard for some brains.

Hay un momento en que el astrónomo, debajo del gran telescopio, se convierte en microbio del microscopio de la luna que se asoma a observarle

By the time I finished high school, I knew I wanted to become an astronomer. By the time I finished college, I knew I wanted to be part of the American space program. And that's exactly what I did.

The age of the universe is not just 'a guess', but rather it is a carefully measured number that is now known to a high degree of accuracy.

I like reading about the astronomical and celestial world a lot.

Even your chin is made up of exploded stars.

If I didn't choose art, I would have become an astronomer.

I meet people on the street who literally chose their careers because they saw 'Back to the Future' and decided they wanted to be scientists or astronomers or engineers.

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

We regard it as a certainty that the earth, enclosed between poles, is bounded by a spherical surface.

Pluto has strong atmospheric cycles: it snows on the surface; the snows sublimate and go back into the atmosphere each 248 year orbit.

The surface of Mars is bathed in ultraviolet light, bathed in radiation. Mars's magnetic field is essentially gone, so the surface of Mars is essentially sterilized.

If you take 10,000 people at random, 9,999 have something in common: their interests in business lie on or near the Earth's surface. The odd one out is an astronomer, and I am one of that strange breed.

The best way to study Mars is with two hands, eyes and ears of a geologist, first at a moon orbiting Mars... and then on the surface.

We were very surprised to find out that Pluto is still geologically alive. It has upended our ideas of how planetary geophysics works.

As for the next nearest star, Proxima Centauri, if you look at it in 2012, what you are seeing is happening in 2008.

Go out into a big field with a football and plonk it down to represent the sun. Then walk 25 metres away and drop a peppercorn to represent the Earth's size and its distance from the sun. The moon, to the same scale, would be a pinhead, and it would be only 5 centimetres away from the peppercorn. But the nearest other star, Proxima Centauri, to the same scale, would be another (slightly smaller) football located about … wait for it … six and a half thousand kilometres away!

It has been estimated that there are between 1 billion and 30 billion planets in our galaxy, and about 100 billion galaxies in the universe.

light from different stars produces 'rainbows' that are different in very particular ways, and this can tell us a lot about the stars.

I suspect that both astronomers were, yet again, bending over backwards to be polite: theologians have nothing worthwhile to say about anything else; let's throw them a sop and let them worry away at a couple of questions that nobody can answer and maybe never will.

In 1846, two mathematical astronomers, J. C. Adams in England and U. J. J. Leverrier in France, were independently puzzled by a discrepancy between the actual position of the planet Uranus and where it theoretically should have been. Both calculated that the perturbation could have been caused by the gravity of an invisible planet of a particular mass in a particular place. The German astronomer J. G. Galle duly pointed his telescope in the right direction and discovered Neptune.

Isaac Asimov ofera o ilustrare dramatica: este ca si cum toata materia din univers ar fi un bob de nisip, asezat in mijlocul unei camere goale cu lungimea, inaltimea si latimea de 32 km. Si totusi, in acelasi timp, este ca si cum acel bob unic de nisip a fost pulverizat intr-o mie de milioane de milioane de milioane de fragmente, pentru ca acesta e numarul aproximativ de stele din univers. Acestea sunt unele dintre faptele astronomiei si puteti vedea cat sunt de frumoase.
