Our Galaxy’s Supermassive Black Hole Constantly Fizzes With Light, JWST Reveals
S agittarius A*, the supermassive black hole (SMBH) at the center of our galaxy, is not as placid as previously thought, new observations with the JWST reveal. Instead, the surrounding accretion disk is flaring almost constantly, with small flares occurring every few seconds, and larger ones several times daily.

Astronomers Suspect Colliding Supermassive Black Holes Left the Universe Awash in Gravitational WavesThe passing gravitational waves “stretch or contract the universe by around 20 meters [about 65 feet] or so,” says Matthew ...
Recently, astronomers focused on a galaxy 270 million light years away, which hosts a supermassive black hole known as 1ES 1927+654. The black hole, researchers have now observed, has been ...
"Our measurements imply that the supermassive black hole mass is 10% of the stellar mass in the galaxies we studied." Using the James Webb Space Telescope (JWST), astronomers have discovered ...
Expect the unexpected In this artist’s rendering, a stream of matter trails a white dwarf orbiting within the innermost accretion disk surrounding 1ES 1927+654’s supermassive black hole.
Supermassive black holes are often regarded as sources of wanton cosmic destruction, but there may be more to their powerful influence than first meets the eye. Researchers studied data from the ...
