The microquasar SS 433 (background) sways with a period of 162 days. The inconspicuous gas cloud Fermi J1913+0515 (foreground), about 100 light years away, pulsates…
A new study reveals what happens when a supermassive black hole in the center of a galaxy cluster stops being active. By combining data from…
Scientists from the University of Valencia detect rapid changes in a black hole that may help understand the origin of gamma-ray bursts. A team from…
The two illustrations on this page show a black hole surrounded by a disk of gas, before (above) and after (below) the disk is partially…
An artist’s impression of the quasar Pōniuāʻena. Astronomers discovered this, the second most distant quasar ever found, using the international Gemini Observatory and Cerro Tololo…
A new theory explains how black holes grow as a function of galaxy mass and eventually quench star formation in their host galaxies. The images…
This diagram shows how a shifting feature, called a corona, can create a flare of X-rays around a black hole. The corona (feature represented in…
