Sample of Brightest Cluster Galaxies
This sample of galaxies, as seen by Hubble, shows chains of star formation in ultraviolet light. This star formation in each galaxy is a product of the action of the jets from a central black hole that controls infalling gas from the galaxy's halo.

Star Formation Triggered by Black-Hole Jets (Artist's Concept)
This artist's rendering shows a central black hole interacting with gas in the galaxy's halo to create a self-regulating cycle. In this cycle, jets shooting out of the galaxy's center heat a halo of surrounding gas, controlling the rate at which the gas cools and falls into the...
