Even though the black hole at the center of the Milky Way is a monster, it`s still rather quiet. Called Sagittarius A*, it`s about 4.6 million times more massive than the sun. Usually, it`s a brooding behemoth. But scientists observing Sgr. A* with the Keck Telescope just observed its brightness blooming to over 75 times normal for a few hours.
