Galaxy is a system of millions or billions of stars, together with gas and dust, held together by gravitational attraction. Galaxies exist in many different sizes, shapes and brightness. They may exist alone or in larger groups called clusters. Galaxies are divided into three basic types: spirals, elliptical and irregulars. The Milky Way is a spiral galaxy where we live.
