In December 2019, an ordinary galaxy 300 million light-years from us in the constellation Virgo suddenly woke up. After decades of inactivity, the black hole at the galaxy's heart burst with light. Now, the cosmic monster appears to be doing something that is forcing astronomers to re-evaluate their understanding of these massive celestial bodies.
The black hole now gives off powerful X-rays at nearly regular intervals. These outbursts are known as quasi-periodic eruptions (QPEs), and have been observed emitting from other black holes. But the bursts observed here are up to 100 times more powerful than normal, according to new research.
Newly 'awakened' black hole is releasing 100 times more energy than scientists have ever seen before
