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

An international team of astronomers has successfully demonstrated a new technique to observe especially faint black holes by ...

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

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 ...

Observations show a stronger galaxy piercing a weaker one with a lance of radiation, reducing its star-making ability.

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 ...

The quasar’s radiation is stripping away gas in its companion galaxy, leaving behind clumps too compact to form new stars.

Astronomers have observed two distant galaxies - both possessing roughly as many stars as our Milky Way - careening toward ...

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 ...

Quasars are a state when a supermassive black hole at the core of a galaxy is feeding at such a rate that it ends up spewing ...
