Black holes are known for their deadly effect on star formation, but this image suggests they may sometimes boost star making.

A composite of radio, optical and X-ray data, this image shows a black hole within a host galaxy (the pink spot near the centre) around 9.9 billion lightyears away.
A gigantic bubble of hot gas generated by the black hole is thought to have expanded and swept through four neighbouring galaxies, creating a shockwave that compressed cool gas, causing stars to form over one million lightyears away.
