    New evidence points to a colossal explosion of the black hole at the center of your universe nearly 2 million years ago.

    A team of researchers led by the University of Sydney says the supermassive black hole at the center of our galaxy, called Sagittarius A*, erupted 2 million years ago with 100 times the power it hastoday. They say the eruption explains the odd glow from the Magellanic Stream that trails behind our galaxy’s two companion galaxies, the large and small Megellanic Clouds, and two huge bubbles of hot gas coming from Sagittarius A* discovered by NASA’s Fermi satellite. They both have matching energies, which indicate an explosion two million years ago.  They say this find is exciting because it confirms that black holes can flicker, or switch on andoff, in short periods of time.
