Overview
Advanced view of Starburst Galaxies
A starburst galaxy is forming stars at an unusually high rate compared with its long-term average and available gas reservoir. Starbursts are intense but temporary because they consume, heat, or expel gas on timescales much shorter than a galaxy's age.
Starbursts reveal how galaxies rapidly convert gas into stars, enrich their surroundings, drive feedback, and evolve after mergers.
