Now, though, using an instrument called the Dark Energy Spectroscopic Instrument or DESI, scientists have discovered a trove of these intermediate black hole candidates. They found 300 promising objects, which is by far the largest group identified to date, and researchers hope to investigate these objects further.

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.

At the center of the Milky Way, a supermassive black hole called Sagittarius A* is never at rest. Using NASA’s James Webb Space Telescope (JWST), researchers have captured the most detailed and longest observation yet of this turbulent cosmic entity.
