Quasars are distant galaxies ... X-Ray Flashes from a Nearby Supermassive Black Hole Accelerate Mysteriously Jan. 13, 2025 — Astronomers observed flashes of X-rays coming from a supermassive ...

Black holes, the densest objects in the universe, eat up anything that comes too close, even light. Is there anything left inside these behemoths that could reveal what they devoured in the first ...

A Michigan State University researcher saw X-rays coming from a black hole using the NASA Chandra X-Ray Observatory telescope. "Every large galaxy has a supermassive black hole, but the exact ...

In a galaxy 300 million light-years away from Earth, a once-quiet black hole has woken up. Astronomers became aware of this galaxy in the Virgo constellation when it abruptly began to light up in ...

Black holes are bounded by outer barriers called event horizons that prevent us from ever viewing their interiors or their hearts, singularities at which all known laws of physics collapse.

"For years, astronomers have searched for a black hole in M83 without success." Scientists have long believed that monster-sized supermassive black holes lurk at the heart of all large galaxies.

Get Instant Summarized Text (Gist) Supermassive black holes can strip subgiant stars of their outer layers, leaving behind dense helium cores. These cores, in close orbit around the black hole ...

These efforts have helped researchers understand the behavior of black holes, the densest objects in the universe where even light cannot escape. Black holes are simpler than you might think.

Another idea, first proposed by respected physicist and mathematician Roger Penrose, is that we could extract energy from rotating black holes, also known as Kerr black holes, after Roy Kerr ...

In the extremely early universe, primordial black holes could acquire a "dark charge," giving them an unnaturally long lifetime. This makes them an interesting, if exotic, candidate for dark ...

Accelerating x-ray flashes could come from the core of a dead star teetering near the event horizon. In 2018 astronomers at MIT and elsewhere observed previously unseen behavior from a black hole ...

Primordial black holes are ancient mysteries, born in the universe’s earliest seconds. Unlike regular black holes, they weren’t formed by collapsing stars. Instead, they emerged when extremely ...
