An international team led by researchers at Oxford University Physics have proved Einstein was correct about a key prediction concerning black holes. Using X-ray data to test Einstein's theory of gravity, their study gives the first…
Black holes seem to provide endless fascination to astronomers. This is at least partly due to the extreme physics that takes place in and around them, but sometimes, it might harken back to cultural touchpoints that made them interested…
Researchers using NASA's Chandra X-ray telescope have found that a group of "Death Star black holes are swiveling around and pointing at new targets, like the fictional space station in Star Wars."
This week, science reporter Isaac Schultz described a groundbreaking effort to measure the spin of a supermassive black hole, and a fascinating experimental archaeology experiment in which marines fought each otherto test how well ancient…
Supermassive black holes that are blasting out beams of high-energy particles killing star formation in their galaxies are shifting targets like real-life Death Stars.
Astronomers have discovered that huge black holes are redirecting powerful beams of particles into space. This discovery, made using NASA's Chandra X-ray Observatory and the National Radio Astronomical Observatory's (NRAO) Very Long…
Astronomers at MIT, NASA, and elsewhere have a new way to measure how fast a black hole spins, by using the wobbly aftermath from its stellar feasting.
Astronomers have a new way to measure how fast a black hole spins, by using the wobbly aftermath from its stellar feasting. The results offer a new way to probe supermassive black holes and their evolution across the universe.
Huge black holes are firing powerful beams of particles into space—and then changing their aim to fire at new targets. This discovery, made using NASA's Chandra X-ray Observatory and the U.S. National Science Foundation (NSF) National…
