In astronomy, starburst is a generic term to describe a region of space with an abnormally high rate of star formation. It is reserved for truly unusual objects.

For example, a very young open cluster can have fairly high star formation rates in its core, but this is an ordinary condition for this object. However, an entire galaxy experiencing the same star formation rate can be described as "starburst".

The Milky Way's Galactic Center is expected to undergo a period of starburst in approximately 200 million years.

They predict that in approximately 200 million years there will be an episode of starburst in the galactic center, with many stars forming rapidly and undergoing supernovae at a hundred times the current rate. The starburst may also be accompanied by the formation of galactic jets as matter falls into the central black hole. It is thought that the Milky Way undergoes a starburst of this sort every 500 million years.
