One of the most massive black holes in the universe lurks at the center of the Cosmic Horseshoe

In 2007, astronomers discovered the Cosmic Horseshoe, a gravitationally lensed system of galaxies about 5.5 billion light-years away. The foreground galaxy’s mass magnifies and distorts the image of a distant background galaxy whose light has traveled for billions of years before reaching us. The foreground and background galaxies are in such perfect alignment that they create an Einstein ring. In 2007, astronomers discovered the Cosmic Horseshoe, a gravitationally lensed system of galaxies about 5.5 billion light-years away.
