Some fast-moving stars within the Milky Way have been traced back to the Large Magellanic Cloud (LMC). In a preprint paper ...

In recent years, astronomers have spotted tantalizing clues that some massive stars turn into black holes before they can eject material outward — in an event they call a failed supernova.

The strange behavior of hypervelocity stars suggests a nearby dwarf galaxy must contain a supermassive black hole. If so, a ...

Hypervelocity stars (HVSs) were first theorized to exist in the late 1980s. In 2005, the first discoveries were confirmed.

But once its fuel runs out, gravity wins: the star implodes, and most of its mass becomes either a neutron star—an ultradense object about the size of a city—or a black hole. The rest explodes ...

Other causes of galaxies suddenly lighting up—such as a supernova (exploding star) or a star getting ripped apart by a black hole—were ruled out because the galaxy remained bright for too long.

Black holes are points in space that are so dense ... In the stellar remnants of a supernova, however, there are no longer forces to oppose that gravity, so the star core begins to collapse ...

If a star orbits a black hole, it will appear from a distance to be orbiting empty space. Gaia projects the star’s orbit on a ...

A fluffy cluster of stars spilling across the sky may have a secret hidden in its heart: a swarm of over 100 stellar-mass black holes.

That means that as a galaxy ages, the supernova deaths of stars are depositing less and less gas in the vicinity of the central accreting supermassive black hole. This means over time, the AGN ...
