NGC 1278 is an elliptical galaxy located about 230 million light-years away[2] in the constellation Perseus.[3] NGC 1278 was discovered by astronomer Heinrich d'Arrest on February 14, 1863. It was then rediscovered by astronomer Guillaume Bigourdan on October 22, 1884, and later listed as IC 1907.[4] NGC 1278 is a member of the Perseus Cluster[5][4] and is a low-luminosity AGN (LLAGN).[6]
One supernova has been observed in NGC 1278: SN 2016ajf (Type Ia-91bg-like, mag. 16.9) was discovered by Kōichi Itagaki on February 18, 2016.[7]
Globular clusters
Unlike the nearby galaxy NGC 1277 which has a dominant population of metal-rich or “red” globular clusters, NGC 1278 has a rich population of both metal-rich and metal-poor or “blue” globular clusters.[8]
