A new computational simulation of the early universe has revealed a fundamental, unbreakable geometric limit to the fabric of spacetime, dubbed the "Metric Wall." Discovered by independent physics ...

Near the black hole (shown in the center), an accretion flow forms a dense, thin thermal disk embedded within a magnetically dominated envelope that helps stabilize the system. The flow is ...

A burst of X-rays from 8 billion years ago may be the first clear evidence of a white dwarf torn apart by a black hole. The study, coordinated by Dongyue Li and Wenda Zhang of the Chinese Academy of ...

In a breakthrough, a team of computational astrophysicists has developed the most comprehensive model of luminous black hole accretion to date. The team used two of the world’s most powerful ...

Some of the brightest beacons in the universe share one hidden engine: matter falling into a black hole. As gas whirls inward, it heats up and shines. In some cases, it also blasts narrow beams of ...

Gravitational waves are energy-carrying waves produced by the acceleration or disturbance of massive objects. These waves, which were first directly observed in 2015, are known to be produced during ...

New simulations suggest magnetic fields hold the key to forming black holes that defy known mass limits. When powerful magnetic forces act on a collapsing, spinning star, they eject vast amounts of ...

Black holes that turn matter into energy could explain dark energy and answer two other cosmic questions. Now, the challenge ...

A new simulation could help solve one of astronomy’s longstanding mysteries—how supermassive black holes formed so rapidly—along with a new one: What are the James Webb Space Telescope’s (JWST) ...

The black hole would have to be within 25 light years from Earth, and we haven’t seen one that close yet. That’s not stopping Cosimo Bambi.

A fluffy cluster of stars spilling across the sky may have a secret hidden in its heart: a swarm of over 100 stellar-mass ...
