Astronomers have spotted displays of flashing lights and “fireworks” near a supermassive black hole at the center of the Milky Way galaxy, a finding researchers said could reveal details about how black holes—among the most mysterious objects in space—behave and interact with their environment.

The James Webb Space Telescope has shown that the Milky Way’s black hole is constantly blazing with light, releasing long flares as well as short flashes every day.
