Black Hole

Astronomers have detected the most distant and powerful "odd radio circle" (ORC) ever observed. These mysterious rings are a relatively recent addition to astronomy, first identified only six years ago. So far, only a few have been confirmed, and they are truly massive -- spanning 10 to 20 times the…

Black holes are eaters of all things, even radiation. But what if their rapacious appetites had an unexpected side effect? A new study published in Physical Review Letters suggests that black holes might spew dark energy—and that they could help explain an intriguing conflict between different measurements of the universe.…

A black hole in a distant quasar is growing faster than the usual limit, according to Chandra observations. This may explain how the first supermassive black holes emerged. Astronomers have identified a black hole growing at one of the fastest rates ever observed. The finding, made with NASA’s Chandra X-ray…

JWST reveals M87's jet (pink) stretching across a hazy violet backdrop, with knots, twists, and even a faint counter-jet streaming from the galaxy's black hole. (Image credit: Jan Röder, Maciek Wielgus et al., Astronomy & Astrophysics (2025)) For more than a century, astronomers have marveled at the brilliant jet of…

The Milky Way’s galactic center (inset) is home to strange, death-defying stars that manage to survive close encounters with our galaxy’s supermassive black hole. New research reveals the unintended side effects of these daring flybys. (Image credit: ESA–C. Carreau) Black holes are often seen as cosmic monsters that swallow anything…

Christian Gralingen Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at astrophysicists for more than a century, but they may finally be on the brink of…

The explosion (circled in red) was marked by repeated gamma-ray bursts over the course of a day. (Image credit: ESO/A. Levan, A. Martin-Carrillo et al.) Astronomers are scratching their heads after detecting a bizarre, long-lasting cosmic explosion unlike anything previously observed. The explosion was a series of repeated outbursts of…

In the vast, mysterious depths of the cosmos, a celestial giant is rewriting the rules of black hole physics. Meet SMSS J052915.80-435152.0, or J0529 for short, a black hole so luminous, so ferocious, and so far away that it’s challenging everything we thought we knew about the universe’s darkest entities.…

Molecular gas and X-ray emission around Sagittarius A*, the Milky Way’s black hole Mark D. Gorski et al. (CC BY 4.0) We have found hot wind blasting out from our galaxy’s supermassive black hole for the first time, which could help us understand its mysterious inactivity. Compared to many other…
