NGC 1189 is abarred spiral galaxy approximately105 millionlight-years away from Earth in theconstellation ofEridanus.[1] It was discovered by American astronomerFrancis Leavenworth on December 2, 1885 with the 26" refractor at Leander McCormick Observatory.[3]
NGC 1189 has extended clumpy star formation throughout its spiral arms with remarkably little associated stellar light, which is striking in the color images.[4]
Together withNGC 1190,NGC 1191,NGC 1192 andNGC 1199 it formsHickson Compact Group 22 (HCG 22) galaxy group.[5] Although they are considered members of this group,NGC 1191 andNGC 1192 are in fact background objects, since they are much further away compared to the other members of this group.[4]
