The black hole’s mass is over half that of all the stars in the surrounding galaxy, a record for any galaxy hosting a quasar. The first-ever sighting of starlight from a galaxy hosting one of the most ...

A quasar is a rare and extremely luminous type of supermassive black hole that is located at the center of a galaxy. NASA's Hubble Space Telescope unexpectedly finds double Quasar in distant universe.

When a supermassive black hole lights up like this, we call it a quasar. To get a good look at quasar jets, astronomers often use radio telescopes. In fact, we sometimes combine observations from ...

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 ...

AI-generated representation of an accreting supermassive black hole, surrounded by gas spiraling toward it along the equatorial plane (the accretion disk) and emitting powerful winds of matter as it ...

When a supermassive black hole lights up like this, we call it a quasar. How to watch a quasar To get a good look at quasar jets, astronomers often use radio telescopes. In fact, we sometimes ...

Artist concept of a growing black hole, or quasar, seen at the center of a faraway galaxy. This artist concept illustrates a supermassive black hole with millions to billions times the mass of our Sun ...

Black holes form when matter collapses to become so dense that spacetime encloses it within an event horizon.This means black holes aren't physical objects in the way they are used to. They aren't ...

Around 100 million black holes are believed to exist within the Milky Way galaxy. Supermassive black holes have masses ranging from millions to billions of times that of the Sun. Located in the ...

Astronomers have discovered a supermassive black hole at the center of a galaxy just 1.5 billion years after the Big Bang that is consuming matter at a phenomenal rate -- over 40 times the ...
