What is a starburst galaxy?
Quick Answer
A starburst galaxy is a galaxy forming stars at an unusually high rate. Its star formation can be dozens or even hundreds of times faster than in calmer galaxies.
The Full Story
Starburst galaxies are characterized by intense episodes of star formation, often triggered by collisions, mergers, or strong gas inflows. Because massive stars burn brightly but live short lives, starbursts can dramatically alter a galaxy’s appearance. Examples include galaxies such as M82, where star formation is concentrated in a compact region. Starburst activity is usually temporary, since it quickly uses up available gas or is interrupted by feedback from supernovae and stellar winds.
