Markarian 231 (UGC 8058) is a Type-1 Seyfert galaxy that was discovered in 1969 as part of a search of galaxies with strong ultraviolet radiation. There are clear signs that a powerful active galactic nucleus is present in the center of the galaxy. It is located about 600 Million light years away from Earth.


The galaxy is now undergoing an energetic starburst. A nuclear ring of active star formation has been found in the center with a rate of formation greater than 100 solar masses per year. It is one of the most ultraluminous infrared galaxies with power derived from an accreting black hole in the center.
