Supermassive black holes in ‘little red dot’ galaxies are 1,000 times larger than they should be, and astronomers don’t know why

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.…

James Webb telescope captures 1st ‘mid-infrared’ flare from Milky Way’s supermassive black hole

(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…

XMM-Newton Detects Mysterious X-Ray Oscillations in Supermassive Black Hole

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…
