The Hubble Space Telescope captured this image of a starburst galaxy located about 300 million light-years away from Earth.

A starburst galaxy is thus named for the incredible rate at which new stars are formed. Hundreds of new stars can be formed from a starburst galaxy in one year, while a “normal” galaxy produces less than a dozen. A parent galaxy needs to be triggered for new stars to be formed. The most common attribution to the creation of new stars is the collision between two galaxies.

The starburst galaxy above, named MCG+07-33-027, is different. Because of its isolation from other galaxies, researchers speculate that it collides with passing galaxies to form new ones.
