NGC 1271

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]
