A galaxy that emits an abnormally large amount of energy in the infrared, radio, ultraviolet, and X-ray portions of the electromagnetic spectrum is known as a starburst galaxy.

Here's why:

* Starburst galaxies are characterized by extremely high rates of star formation.

* This intense star formation produces a tremendous amount of energy across a wide range of the electromagnetic spectrum.

* The young, hot, massive stars in these galaxies emit strongly in ultraviolet and X-rays.

* The dust heated by these stars emits strongly in the infrared.

* The supernovae that occur frequently in starburst galaxies contribute to radio emission.
