Artist's Impression of a Starburst Galaxy

This illustration shows a messy, chaotic galaxy undergoing bursts of star formation. This star formation is intense; it was known that it affects its host galaxy, but this new research shows it has an even greater effect than first thought. The winds created by these star formation processes stream out of the galaxy, ionizing gas at distances of up to 650,000 light-years from the galactic center.
