NGC 1270 is an elliptical galaxy located about 250 million light-years away[2] in the constellation Perseus.[3] It was discovered by astronomer Heinrich d'Arrest on February 14, 1863.[4] NGC 1270 is a member of the Perseus Cluster[5][4] and has an estimated age of about 11 billion years.[6] However, Greene et al. puts the age of NGC 1270 at about 15.0 ± 0.50 Gy.[7]

NGC 1270 has a supermassive black hole[8] with an estimated mass of no more than 12 billion solar masses (12×109 M☉).[9]

Activity

Spectroscopy of NGC 1270 suggests that the galaxy contains a low-luminosity AGN (LLAGN).[10]
