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.

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.

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

Astronomers have spotted the biggest pair of black hole jets ever seen, spanning 23 million light-years in total length. That's equivalent to lining up 140 Milky Way galaxies back to back.

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

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

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 ...

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

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.

A new study reveals that one such pair of jets, belonging to a black hole some 7.5 billion light-years away, stretches some 23 million light-years—the equivalent of placing 140 Milky Ways in a ...
