Starburst

Definition

Starburst is a period of intense star formation in a galaxy, often triggered by a merger or interaction with another galaxy. During this phase, the rate of star formation can be up to 100 times higher than usual.

5 Must Know Facts For Your Next Test

1. Starbursts are often associated with galaxy mergers and interactions.
2. A starburst can significantly alter the structure and evolution of a galaxy.
3. These events can pave the way for the development of active galactic nuclei (AGN).
4. Starbursts can lead to rapid consumption of gas and dust, fueling stellar nurseries.
5. Infrared observations are critical for studying starbursts due to heavy dust obscuration.
