NGC 1271
Galaxy in the constellation Perseus
From Wikipedia, the free encyclopedia
NGC 1271 is a compact elliptical or lenticular galaxy[2] located about 250 million light-years away[4] in the constellation Perseus.[5] The galaxy was discovered by astronomer Guillaume Bigourdan on November 14, 1884.[6] NGC 1271 is a member of the Perseus Cluster[7][6] and has a nuclear dust disk in its center.[3] It also has an edge-on, intermediate-scale disk and has a central bulge.[2] Like NGC 1277, NGC 1271 is a candidate "relic galaxy".[8]
