Starburst galaxy
A starburst galaxy is a galaxy in the process of an intense burst of star formation, often as a result of a collision or close encounter between two galaxies. Normal galaxies also form stars, but at a much lower rate.

STARBURST GALAXY
A starburst galaxy is a bright, blue-glowing that has a high rate of star formation (sometimes, the star-formation area is only at the core of the galaxy, and these galaxies are called nuclear starbursts).

M82, the archetype starburst galaxy, has experienced a 10-fold increase[60] in star formation rate as compared to a "normal" galaxy.
This peculiar starburst galaxy in Ursa Major was discovered by Bode in December 1774 and Messier observed it on February 9, 1781. It shows signs of large scale explosions and contrasts with M81 located about 40' S.
May's Hubble Heritage image is of the starburst galaxy M82, AKA NGC 3034, AKA The Cigar Galaxy. 12 million light-years from us, the galaxy lies in the constellation Ursa Major; this image covers approximately 7.
With Chandra, Weaver studied the galaxy NGC 253, a relatively nearby, classical starburst galaxy about 10 million light-years from Earth. This galaxy had no prior evidence of an X-ray-emitting AGN.
NGC 4666 is known as a starburst galaxy because it is giving birth to thousands of new stars. The process is driven by interactions with nearby galaxies, such as NGC 4668, which is at lower left.
Approximately 12 million light-years distant, it is a prototype starburst galaxy, one that is five times as bright as our own galaxy, the Milky Way, and about a hundred times brighter than the Milky Way's centre.

A starburst galaxy may result when a galaxy experiences a close encounter with a neighbor. The strong tidal distortions caused by the encounter compress galactic gas, resulting in a widespread burst of star formation.

which are forming enormous numbers of new stars and are thus extremely bright in the infrared. Further infrared studies of these galaxies may find the cause of this star-forming frenzy. At the left is a 2MASS infrared image of a starburst galaxy.
Such interactions between nearby galaxies, which may ultimately result in galaxies merging, may induce episodes of significantly increased star formation, producing what is called a starburst galaxy.
