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

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, ...

NASA’s James Webb Space Telescope has recorded another amazing achievement. Scientists announced Tuesday that the telescope ...

A supermassive black hole in the Large Magellanic Cloud (LMC) may be the source of nine stars zooming through our galaxy – a surprising hint that dwarf galaxies can host large black holes.

The centers of galaxy clusters contain the universe’s most massive galaxies, which, in turn, contains gigantic black holes ranging in mass from millions to tens of billions of times that of the ...

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.

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 ...

That's because the spin rates reveal something about the black holes' formation history. "Unexpectedly, we found that they were spinning too fast to have been formed by galaxy mergers alone," he said.
