For decades, physicists imagined harnessing the exotic physics of black holes ... the waves can shift into negative frequencies — a rotational version of the Doppler effect.

No telescope? No problem. These astronomy apps turn your phone into a sky guide perfect for spotting stars, planets, and ...

Gaia, which stands for Global Astrometric Interferometer for Astrophysics, has nothing to do with the Greek goddess of the ...

Astronomers have spotted a supermassive black hole ripping apart and devouring a star in colliding galaxies. It is only the ...

The sneaky black hole betrayed its presence in a newly identified tidal disruption event (TDE) where a hapless star was ripped apart and swallowed in a spectacular burst of radiation. These ...

Ever since general relativity pointed to the existence of black holes, the scientific community has been wary of one peculiar feature: the singularity at the center—a point, hidden behind the ...

Astronomers have observed a tidal disruption event, AT2024tvd, caused by a rogue supermassive black hole devouring a star far from its galaxy's center. This marks the first time a TDE has been ...

Now, about a year later, we know it's the first tidal disruption event—meaning a star being ripped apart by a supermassive black hole—identified at visual wavelengths. It's also a rather ...

A supermassive black hole around a million times the mass of the Sun just gave away its position in spectacular fashion. When a passing star veered a little too close, it was torn apart in the ...

The Hubble Space Telescope captures an image of a supermassive black hole that is not at the center of its galaxy. Credit: NASA / ESA / STScI / Yuhan Yao / Joseph DePasquale Using NASA's Hubble ...

On each pass, the star kicks out one Jupiter's worth of mass from the black hole's disk. A star in a faraway galaxy is sending itself into a spiral of doom, repeatedly plunging through a disk of ...

That is a black hole. There are a few defining characteristics for these objects. They tend to have an event horizon, the surface that separates them from the rest of the universe – once you ...
