One of the lowest mass supermassive black holes ever observed in the middle of a galaxy located in the middle of the spiral galaxy NGC 4178, is shown in this image from the Sloan Digital Sky Survey released on October 25, 2012. An analysis of the NASA's Chandra X-ray Observatory data, along with infrared data from NASA's Spitzer Space Telescope and radio data from the NSF's Very Large Array suggests that the black hole is near the extreme low-mass end of the supermassive black hole range. NGC 4178 is a spiral galaxy located about 55 million light years from Earth. (Photo by Reuters/NASA/CXC/George Mason Univ)
