Ones forming new components at an unusually high rate are known as starburst ones.
Central dominant types of these objects become large due to collisions. Ones forming new components at an unusually high rate are known as starburst ones. According to Hubble's law, more distant ones of these objects move away faster the more distant they are. If these objects are not irregular they are either elliptical, barred spiral, or spiral. For 10 points, name this term for a group of stars bound by gravity and orbiting together, such as the Andromeda one or our Milky Way.
