DESI, which will be scanning the sky for five more years, is expected to observe around 40 million galaxies and quasars ...

The two black holes tracked by the Event Horizon Telescope were both of this type. Sagittarius A* (Sag A* for short) is smack in the middle of the Milky Way, some 26,000 light years from Earth.

So far, astronomers have identified three types of black holes: stellar black holes, supermassive black holes and intermediate black holes. Black holes formed by the collapse of individual stars ...

Ancient quasars seen by the James Webb Space Telescope technically shouldn’t exist, but one rare type of dark matter could make sense of that. Ultra-self-interacting dark matter clumped into ...

Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity. And anything that ...

Rotating black holes are the most powerful phenomenon in the known universe. Their powerful gravity radically alters the ...

Astronomers have uncovered a baffling cosmic anomaly — a supermassive black hole in galaxy NGC 5084 that appears to be ...

This type of magnification is called gravitational lensing and was first predicted by Albert Einstein in 1915. Now, new ...

The disc of plasma surrounding the black hole at the heart of the Milky Way is constantly emitting flares both large and small.

More specifically, through a large, rotating black hole, which is where these types of singularities exist. Now, astronomers obviously can't travel through a black hole yet to test this theory.

If black holes follow the example of the legendary ... Waves are at the heart of both types of radiation, and they have properties like wavelength, the distance between two peaks in a wave ...
