The black hole at the center of our Milky Way galaxy just got about 75 times brighter.
Astronomers have no idea why.
This is the brightest we have ever observed.
This happened in the span of just a few hours. This is the brightest it has been since scientists first started studying it more than 20 years ago.
Sagittarius A* is the bright and very compact astronomical radio source at the center of the Milky Way.
It is likely the location of a supermassive black hole, similar to those generally accepted to be at the centers of most if not all spiral and elliptical galaxies.
