The black hole powering a quasar 13 billion light-years from Earth is half as massive as all the stars around it — a record high ratio for a quasar host galaxy, astronomers report in a paper ...

This light, trillions of times brighter than the sun, indicates a quasar. However, supermassive black holes need a "delivery ...

Using the James Webb Space Telescope (JWST), astronomers have spotted the earliest powerful "galaxy-size" wind blowing from a ...

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 ...

It's a quasar - the bright core of a galaxy that is powered by a gargantuan black hole some 17 billion times the mass of our Sun. Known as J0529-4351, the object's power was confirmed in ...

In a few tens of millions of years, the black holes and their galaxies will merge, and so will the quasar pair, forming an even more massive black hole.
