Black hole ‘volcanic eruptions’ influence vast areas of intergalactic space, study shows


Bubbles of gas released by black holes spread across vast distances of the intergalactic space, affecting star formation thousands of lightyears away from their source, a new study shows. 

Astronomers knew that black holes draw in matter from their surroundings due to their powerful gravitational pull. They also previously documented that some of this matter subsequently escapes in the form of jets of charged particles that squirt out at the speed of light out of the black hole’s poles.
