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 ...

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

Researchers have shown that abstract mathematical functions from the frontiers of theoretical physics have a real-world use ...

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

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

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 ...

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