However, unlike other spiral galaxies found scattered throughout the universe, the black hole which is assumed to exist in the center of the Milky Way galaxy is dormant and is not "actively feeding," meaning that it is not currently swallowing up material for some unknown reason. Almost from the beginning of astronomical observations of galactic bodies in the universe, it has always been thought that "the more massive the bulge, the more massive the black hole" which has led scientists and astronomers to reason that "somehow the formation and growth of galaxy bulges and their central black holes are intimately connected." But in 2003 when the Spitzer Space Telescope began to be utilized to collect infrared data from a number of different types of galaxies, scientists discovered that thin or slender galaxies which lack prominent central bulges did indeed contain supermassive black holes.

During a recent study with the Spitzer...
