ESO 269-57 is a largebarred spiral galaxy located about 150 millionlight-years away[2] in theconstellationCentaurus. ESO 269-57 has a diameter of about 200,000light-years.[3] It is part of group of galaxies known as LGG 342.[4][5] which is also known as theNGC 5064 Group[6][4] which is part of theCentaurus Supercluster.[6]
ESO 269-57 has an inner ring surrounding its bright center and connected by its bar. The ring is made up of several tightly wound spiral arms. Surrounding the inner ring, are two outer arms made up ofstar-forming regions that appear to split into several branches of arms.[3]
On March 3, 1992 atype Ia supernova was discovered in ESO 269-57.[7]
