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…
The solar dynamo that drives sunspots and solar flares could be located near the surface of the sun scientists find, solving a 400-year-old solar mystery and providing a weird link to black holes.
A new study offers a fascinating new method to measure the spin speed of a black hole. This ability could help astronomers flesh out how our universe came to look as it does today.
A team of astronomers has managed to calculate the speed of a distant supermassive black hole’s spin thanks to the object’s chance meeting with a star—which it promptly destroyed.
