Sagittarius A*, our galaxy's supermassive black hole, is constantly producing strange eruptions. Astronomers are using the ...

NASA telescope captures the most detailed glimpse yet of the black hole in the middle of our galaxy - Scientists hope that ...

Back in 1971, a couple of British astronomers predicted the existence of a black hole at the center of our galaxy. And in 1974, other astronomers found it, naming it Sagittarius A*. Since then, ...

This discovery explains how massive galaxy clusters evolved into the dormant, giant elliptical galaxies seen today, shedding light on the co-evolution of black holes and galaxies. Galaxy clusters ...

In the modern universe, for galaxies close to our own Milky Way, supermassive black holes tend to have masses equal to around 0.01% of the stellar mass of their host galaxy. Thus, for every 10,000 ...

Astronomers have, for the first time, watched the moment a feeding supermassive black hole at the heart of a distant galaxy spat out a jet of material at one-third of the speed of light.

The other suspect is a supermassive black hole shredding a star. But a galaxy that small probably lacks both. “We think an intermediate-mass black hole is a really good candidate,” she says.
