Webb Catches Mysterious Light Flares Around Milky Way's Supermassive Black Hole
Between spotting galaxies that shouldn't exist, capturing the interstellar medium with unprecedented clarity, and identifying new worlds, the James Webb Space Telescope is a busy observatory. But as it orbits the Sun,
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.
"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 ...

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 ...
Back in 1971, a couple of British astronomers predicted the existence of a black hole at the center of our galaxy. And in 1974, other astronomers found it, naming it Sagittarius A*. Since then, ...
Ultra-self-interacting dark matter clumped into supposedly enormous masses that collapsed in on themselves and created the supermassive black holes in these quasars. Scientists formulated a ...
Within the Dark Energy Spectroscopic Instrument's early data, scientists have uncovered the largest samples ever of intermediate-mass black holes and dwarf galaxies hosting an active black hole, more ...
The supermassive black hole has been sending out flashes that have increased in speed. Astronomers say they have never seen anything like it before. The black hole is known as 1ES 1927+654 ...
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.
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 ...
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 ...
