# X-ray flashes from a supermassive black hole

!(70%)[Black hole](img/blackhole.jpg)

.abstract One supermassive black hole has kept astronomers glued to their scopes for the last several years. The black hole in question is `1ES 1927+654`, which is about as massive as a million suns and sits in a galaxy that is 270 million light-years away. In 2018, astronomers at MIT and elsewhere observed that the black hole’s corona — a cloud of whirling, white-hot plasma — suddenly **disappeared**, before reassembling months later. The brief though dramatic shut-off was a first in black hole astronomy.
