Photo of the day: Spiral galaxy stretches its cosmic armsThe four arms of the Messier 106 galaxy are seen in this stunning new photo taken by the Hubble Telescope. Located 20 million light-years from Earth in the Ursa Major constellation, the center of Messier 106 serves as host to a monster black hole. Although most spiral galaxies just have two arms, Messier 106 boasts four cosmic appendages. In addition to the prominent limbs comprised of millions of stars, there are also two wisps of gas (seen in red) that are believed to be caused by the galaxy’s ravenous black hole.
