Scientists have discovered that a mysterious black hole has begun exhibiting unusual behavior. This supermassive black hole is emitting light and has accelerated in speed, a phenomenon astronomers have never observed before. Named 1ES 1927+654, the black hole is millions of times the mass of the sun and resides in a galaxy millions of light-years away from Earth. In 2018, scientists observed it as a rotating hot plasma that suddenly disappeared, only to reappear months later, an occurrence previously unseen. Erin Kira, Associate Professor of Physics at MIT and co-author of the research, stated that they had been observing it from the beginning because it was fascinating, but later they observed something unprecedented.
