But in the past two decades, new types of black holes have been seen and astronomers are beginning to understand how they ...

Astronomers have witnessed a distant supermassive black hole devouring its surrounding matter so rapidly that it is "burping" out excess mass at nearly a third of the speed of light.

"Theories involving substantial formation of stars prior to or together with the black hole formation and growth are very ...

Black holes are remarkable astronomical objects with gravity so strong that nothing, not even light, can escape them. The most gigantic ones, known as "supermassive" black holes, can weigh millions to ...

ENTs occur when stars that are at least three times as massive as the Sun pass so close to a supermassive black hole that its ...

Gravitational waves spotted by LIGO reveal two black holes, 140 and 100 times the mass of the sun, merged to become a 225 solar mass behemoth.

Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...

Quasar 0957+561, the first known gravitationally lensed quasar, lies near NGC 3079 in Ursa Major. Here's how to find and ...

Names are a strange thing in astronomy. Sometimes scientists come up with grandiose, simple name, like the Extremely Large ...

In summer, we face toward the Milky Way's hub in the Teapot constellation, home to the galaxy's supermassive black hole.

Supermassive black holes should be pretty hard to miss. Just like Sagittarius A*, the black hole at the center of the Milky Way is. While you can’t expect see them by going outside and looking ...
