Besides particles like sterile neutrinos, axions and weakly interacting massive particles (WIMPs), a leading candidate for ...

Some stars streaking through the Milky Way at millions of kilometers per hour probably trace back to a supermassive black ...

When people think of black holes, they imagine something dramatic: a star exploding in space, collapsing in on itself, and ...

Supermassive black holes are behemoths that weigh in at several million to billion times the mass of our own sun. Like their ...

The moment one galaxy spears another with a powerful beam of radiation shooting from its central black hole has been spotted in a distant galactic collision.

Astronomers searching for massive black holes shredding stars found one in an unusual place -- 2,600 light years from the core of a galaxy. The roque black hole may be from an earlier merger with ...

A binary system 18,000 light-years away, emits X-rays as a Sun-like star orbits a dense companion, either a neutron star or black hole. Telescopes like Chandra, IXPE, and XMM-Newton capture its ...

Using NASA 's Hubble Space Telescope and other observatories, astronomers found the cosmic object in an unexpected place.

An experimental setup mimics a “black hole bomb” first theorized in 1971. The spinning cylinder with circuitry is true to the ...

Astronomers watched as a galaxy with the forgettable name SDSS1335+0728 suddenly sprang to life when its massive black hole ...

NASA and JAXA discovered a fascinating superstorm from a black hole that may reshape galaxies by triggering star formation ...

Black holes form when a massive star collapses in on itself because of its own gravity after it has burned all of its nuclear fuel. Black holes are invisible, but it could be possible to deduce ...
