Astronomers have discovered extraordinarily powerful X-ray jets blasting from two supermassive black holes that are so ancient that the jets shine in the afterglow of the Big Bang.

Twin orbs of superhot plasma at the Milky Way's center known as the "Fermi bubbles" contain inexplicable clouds of cold ...

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

Astronomers have spotted a massive pair of jets releasing material from a distant black hole. The jets are so large they span about 140 Milky Way galaxies in length.

The new black hole has more than 200 times the mass of our sun – and is challenging theories of how objects form in space ...

Astronomers have seen the largest jets ever found erupting from a black hole. The giant jet system Porphyrion is 23 million light-years long, equal to 140 side-by-side Milky Way galaxies.

One of the most powerful objects in the universe is a radio quasar – a spinning black hole spraying out highly energetic particles. Come too close to one, and you’d get sucked in by its gravitational ...

A U.S. gravitational wave detector spotted a collision between fast-spinning “forbidden” black holes that challenge physics ...

Two mighty beams of energy have been detected shooting in opposite directions from a supermassive black hole inside a distant galaxy - the largest such jets ever spotted, extending about 140 times ...

A pair of jets blasting out of a black hole spans 23 million light years, the equivalent of 220 Milky Way galaxies in length. This is so large that it may change our understanding both of black ...

Particles orbiting a black hole could collide at colossal energies, generating collision products that may offer valuable ...

These are rare occurrences—scientists estimate that the giant black hole at the center of our Milky Way galaxy gobbles a star ...
