Scientists have spotted the brightest flare yet from a black hole. It was first spotted in 2018 by a camera at the Palomar Observatory in California. The cosmic outburst likely happened because a large star wandered too close to the black hole and got shredded to pieces. It took about three months to shine at peak brightness, about the light of 10 trillion suns. Almost every large galaxy, including our Milky Way, has a supermassive black hole at its center. Studying such behemoths can help researchers understand the stellar neighborhood surrounding them. The research was published Tuesday in the journal Nature Astronomy.
