The Event Horizon Telescope only recently gave us the first images of the environment immediately surrounding a black hole.

“We showed that if black hole morsels are created during mergers, they would produce a burst of high-energy gamma rays, with the delay time related to their mass,” Dr. Cacciapaglia said. “Our analysis ...

The ground may feel steady underfoot, but the planet is always in motion. While satellites and sensors have mapped the surface in fine detail, what lies beneath remains largely unknown. The crust, a ...

A black hole can feel like the most distant and unreal object you could ever think about, yet the way its darkness bends ...

Active galactic nucleus (AGN) black hole 10 billion light-years away, J2245+3743, made the biggest and brightest flare ever ...

Yet according to physics, information is never destroyed. In principle, a burned book is just as readable as the original—if ...

Why it's incredible: Evidence suggests it could be the greatest known impact crater on Earth. The Wilkes Land crater is a hole in the bedrock beneath East Antarctica's ice sheet measuring 315 miles ...

The gravitational wave observatory LIGO has returned its second set of results, featuring two light-weight black holes perfect for making detectable gravitational waves. Share on Facebook (opens in a ...

Physicists have taken a new approach to whether all black holes conform to Einstein’s theory of general relativity or if ...

Astronomers were baffled after they observed a mid-infrared flame from the central black hole of the Milky Way. It lasted for nearly an hour, which led scientists to new clues on how the outbursts ...
