The AI also provided insights into the black hole's emission source and magnetic field behavior. Edited by: Nikhil Pandey Science Jun 19, 2025 22:55 pm IST Read Time: 3 mins ...

An artist’s impression of a tidal disruption event, in which a star is spaghettified and the remains form an accretion disk around the black hole. Typically, about half the star’s mass is drawn into ...

About 99 percent of all the mass released in a tidal disruption event is called nonrelativistic—it moves along at 10 percent the speed of light or less. The remaining 1 percent, however, is very ...

A simulation of a heavy black-hole merger (GW190521) emitting gravitational waves. N. Fischer, H. Pfeiffer, A. Buonanno (Max Planck Institute for Gravitational Physics), Simulating eXtreme ...

A supermassive black hole in the early Universe has been spotted blasting out powerful jets of plasma that are at least twice as long as the Milky Way is wide. Its host galaxy is a quasar called ...

Using a neural network trained with simulations of supermassive black holes, astronomers have found that the one at the center of the Milky Way, Sagittarius A*, likely rotates at maximum speed.

General relativity was developed by Einstein and successfully explains large-scale phenomena like planetary orbits, black holes, and the expansion of the universe. Quantum mechanics, developed in the ...

The monster black hole lurking at the center of galaxy M87 is an absolute beast. It is one of the largest in our vicinity and was the ideal first target for the Event Horizon Telescope. Scientists ...

Spinning close to universal limits The black hole weighs about 6.5 billion solar masses. Scientists now believe it spins at around 80% of the maximum speed nature allows.

SIOUX FALLS, S.D. (KELO) — Rescue crews in the Black Hills were called to help an injured hiker over the weekend. The Rockerville Volunteer Fire Department says it happened just after p.m. Sa… ...
