NASA's James Webb Space Telescope has detected cosmic flares around the supermassive black hole at the center of our Milky Way galaxy.
The accretion disk of hot gas surrounding the black hole throws off about five or six big flares a day, along with smaller bursts.
The flares are believed to be caused by turbulence and magnetic reconnection events in the accretion disk.
Observations at two near-infrared wavelengths revealed a slight time delay in brightness changes, providing insights into the physical processes at work in the disk.
