ESO 269-57 is a large spiral galaxy located about 150 million light-years away[2] in the constellation Centaurus. ESO 269-57 has a diameter of about 200,000 light-years.[3] It is part of group of galaxies known as LGG 342.[4][5]
Physical characteristics
ESO 269-57 has an inner ring surrounding its bright center. The ring is made up of several tightly wound spiral arms. Surrounding the inner ring, there are two outer arms which are made up of star-forming regions that appear to split into several branches of arms.[3]
