The research, posted to the arXiv preprint server, is titled "The disappearance of a massive star marking the birth of a black hole in M31." The lead author is Kishalay De, a postdoctoral scholar ...

We’ve never been looking at a black hole and watched it go from being radio quiet to suddenly very radio loud,” Meyer said. Essentially, her team witnessed the birth of jets from a ...

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

Following is the transcript of the video. Narrator: Black holes are some of the most powerful and violent objects in the universe. They can warp space and time and rip entire stars to pieces.

This particular black hole was adding material at a slow rate ... Meyer believes the data in this case point most strongly to the birth of a new CSO. One recent hypothesis is that jets in ...

Gravitational waves are unlocking the origins of black holes, linking spin shifts to sequential mergers in star clusters.

Observations from NASA's Chandra X-ray telescope and the VLT have revealed jets blasting from supermassive black holes cause gas to cool and fall toward them in a cosmic feeding process.

Einstein’s new theory of gravity, known as general relativity, gave birth to a monster that he never escaped: the black hole, a cosmic entity with the mass of millions or billions of suns that ...

Rather than relying on a cheek swab or a little blood, however, these cosmic DNA tests utilize tiny ripples in the fabric of spacetime called gravitational waves, first proposed by Albert Einstein 110 ...

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