From Wikipedia

A galaxy is the group of millions of stars, gas, dust, and dark matter. Galaxies are held together by gravity. Everything in the galaxy moves around the center.

Our Galaxy is called the Milky Way.

There are three main types of galaxies: ellipticals, spirals, and irregulars.

Galaxies are grouped together in groups of galaxies.

Groups of galaxies are grouped together in galactic superclusters.
