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…

This artist’s concept shows a supermassive black hole surrounded by a disk of gas. Embedded in this disk are two smaller black holes that may…
Possible light flare observed from small black holes within the disk of a massive black hole. When two black holes spiral around each other and…
In August of 2019, the LIGO-Virgo gravitational-wave network witnessed the merger of a black hole with 23 times the mass of our sun and a…
Visualization of the coalescence of two black holes that inspiral and merge, emitting gravitational waves. One black hole is 9.2 times more massive than the…
