Galaxies
A galaxy is a large collection of stars, dust and gas. They are surrounded by dark matter, and are held together by gravity.

Within these clouds are numerous bright white dots of stars, though some appear more blue or red in colour. There are also a few stars visible against the black background.](/sites/default/files/styles/things_to_do_photovidppt/public/Blackeyegalaxy.jpg?itok=W31BvOUO)
