An image captured by NASA's Hubble Space Telescope reveals details about a galaxy formed when a larger galaxy absorbed one of its satellite galaxies, the Space Telescope Science Institute announced. Messier 64 is known as the Black Eye galaxy because the collision of the two star clusters left a dark band of dust in front of its nucleus. The galaxy is unique because while its stars rotate in a clockwise direction, interstellar gas in the outer region rotates in the opposite direction. The opposite rotation was created when the smaller galaxy was absorbed, according to a statement released by the institute Feb. 5.
