"We would need to consider the possibility that the source was created (or trapped as a primordial black hole) by a highly advanced technological civilization," Harvard's Avi Loeb writes.

Using the XMM-Newton telescope, astronomers have witnessed high-speed "burps" erupting from a distant overfeeding ...

Caltech simulations reveal what happens when black holes collide with neutron stars—violent cracking, intense shock waves, ...

Through this AI technique, they generated a new image of Sagittarius A*'s structure, and their picture revealed some new features. For example, the black hole appears to be spinning at "almost top ...

Sagittarius A* is spinning near top speed with its rotation axis pointing towards Earth. Event Horizon black hole project executed over 12 million computing jobs using distributed computing.

The black hole couldn’t handle all the material it had pulled in, so it expelled some of it in a powerful outflow. This outflow was moving at 27% the speed of light, or about 80,000 kilometers ...

A powerful new technique is poised to revolutionize how astronomers observe black holes, by producing sharp, multicolored images that could reveal their dynamic evolution in real time.

An artist’s impression of a tidal disruption event, in which a star is spaghettified and the remains form an accretion disk around the black hole. Typically, about half the star’s mass is drawn into ...

There are objects in our universe so dense that not even light escapes through them. These oddities, known as supermassive black holes, can weigh billions of times more than our sun. Scientists have ...
