How much do you know about astronomy? Astronomy has the ability to fascinate and astound. Looking into the skies, and studying the planets, stars and galaxies, has long enthralled people on earth. Do you know that light from the sun takes eight minutes to reach earth? Do you know that Saturn would actually float if it was in a giant pool of water, as it is less dense?

Did you know that the rings of Saturn were first described by Galileo as “ears”? Do you also know that the view we have of the Andromeda Galaxy is from 2.3 million light years away, so we see the galaxy as it was 2.3 million years ago. Astronomy is a fascinating subject.
