Mysterious stars surround Andromeda's Black Hole.
Fermi Bubbles: Discovered in 2010 by NASA's Fermi Gamma-ray Space Telescope, the so-called radiation-emitting Fermi bubbles emanating from the center of the galaxy are each 25,000 light years (147,000 trillion miles) tall. Visible to gamma-ray telescopes, the bubbles jut from the top and bottom of our spiral-shaped galaxy like doorknobs on both side of a door. via usatoday.
