Quasars — galactic cores containing active supermassive black holes — are among the most ancient things in the universe. As dust and gas accelerate toward the quasar's central black hole, the ...

Using the James Webb Space Telescope (JWST), astronomers have gotten the first-ever look at the light of ancient stars shining around some of the biggest, brightest and oldest black holes in the ...

Astronomers have observed matter plunging into the mouth of a black hole at the speed of light, proving a key prediction made by Einstein right, yet again. In 1915, Einstein's general theory of ...

Astronomers have witnessed vast black holes blasting powerful beams of particles into space, and then changing aim and firing at new celestial targets. This cosmic firing range, which is reminiscent ...

May 29, 2024 — Researchers have applied the well-understood and highly verified quantum field theory, usually applied to the study of the very small, to a new target, the early universe.

Over 100 years on, scientists have finally confirmed one of Albert Einstein's theories about the nature of black holes. In 1915, Einstein predicted that black holes should have a 'plunging ...

The "wobbling" remains of a star that suffered a grisly death at the maw of a supermassive black hole has helped reveal the speed at which its cosmic predator spins. Supermassive black holes are ...

Einstein’s theory predicted that this final plunge would exist. Contrary to Newton’s theory of gravity, Einstein’s theory posits that particles cannot safely follow circular orbits when near a black ...
