When two enormous black holes collide in deep space, they send shockwaves rippling across the universe. These shockwaves, ...

Our understanding of black holes, time, and the mysterious dark energy that governs the universe may be on the verge of a ...

"Most black holes form from the remnants of a large star ... in Chile captured the aftermath of the explosion from "Gamma-Ray Burst GRB221009A." Credit: International Gemini Observatory / NOIRLab ...

Black holes are points in space that are so dense ... enormous stars go out with a bang in massive explosions known as supernovae. Such a burst flings star matter out into space but leaves behind ...

"The higher the spin, the more energy the black hole can release." Black holes may leak more energy to their surroundings than previously suspected — and the faster these voids spin, the more ...

A new study using NASA 's James Webb Space Telescope has revealed a variety of light coming from the black hole Sagittarius A* — or rather its accretion disk, the ring of rapidly spinning material ...

A big burst of brightness suddenly popped up ... "The activity profile of this black hole was new and exciting every time that we looked at it." Though they're effectively invisible, astronomers ...

In these cases, the core of the star collapses to be a super-compressed, spinning black hole, which stirs and energize the wreckage around it to briefly emit a tremendous burst of gamma rays.

Feb. 19, 2025 — Within the Dark Energy Spectroscopic Instrument's early data, scientists have uncovered the largest samples ever of intermediate-mass black holes and dwarf galaxies hosting an ...

This preferred direction of spin might be due to one of two reasons: either our entire universe exists in a black hole, or astronomers have been measuring the universe's expansion incorrectly ...

Black holes have a profound impact on their environments ... showing X-ray “echo” from an accretion disk evolves over time in response to an intense burst of X-rays somewhere above the disk. The first ...
