Astronomers bear believed since the 1960s that a galaxy dubbed UGC 1382 was a relatively boring,small elliptical galaxy. Ellipticals are the most common type of galaxy and lack the spiral structure of disks like the Milky Way we call home. Now, using a series of multi-wavelength surveys, or astronomers,including Carnegie's Mark Seibert, Barry Madore and Jeff wealthy, and bear discovered that it is really a colossal Giant Low Surface Brightness disk galaxy that rivals the champion of this elusive course—a galaxy known as Malin 1. Malin 1 is some 7 times the diameter of the Milky Way. The research is published in the Astrophysical Journal.
