These eerie wails are a real sound wave from a supermassive black hole NASA created a haunting audio clip of sound waves rippling out of a supermassive black hole, located 250 million light-years away. The black hole is at the center of the Perseus cluster of galaxies, and the acoustic…

An illustration shows seven "little red dot" galaxies embedded in the cosmic web, one of which is dominated by a supermassive black hole (Image credit: Robert Lea (created with Canva)) Using the James Webb Space Telescope (JWST), astronomers have discovered distant, overly massive supermassive black holes in the early universe.…

Astronomers have taken a crucial step in showing that the most massive black holes in the universe can create their own meals. Data from NASA’s Chandra X-ray Observatory and the Very Large Telescope (VLT) provide new evidence that outbursts from black holes can help cool down gas to feed themselves.…

(Image credit: © CfA/Mel Weiss) The James Webb Space Telescope (JWST) has detected a flare from the supermassive black hole at the center of the Milky Way — and it could help explain why these strange outbursts occur.. Sagittarius A* is 4 million times the mass of the sun and…

In 2018, astronomers observed that the corona of 1ES 1927+654, an actively accreting, 1.4-million-solar-mass black hole located in a galaxy around 270 million light-years away, suddenly disappeared, before reassembling months later. The brief though dramatic shut-off was a first in black hole astronomy. Now, astronomers using ESA’s XMM-Newton observatory caught…
