The Galaxies
A galaxy is a group of many stars, with gas, dust, and dark matter. The name 'galaxy' is taken from the Greek word galaxia meaning milky, a reference to our own galaxy, the Milky Way. Gravity holds galaxies together against the general expansion of the universe. A galaxy can contain anywhere from a billion stars to over a trillion. Our own Milky Way Galaxy contains about 100 - 400 billion stars. Our closest galatic neighbor, the Andromeda galaxy contains about 1 trillion of them.
