NGC 4070 is an elliptical galaxy located 340 million light-years away[2] in the constellation Coma Berenices.[3] NGC 4070 was discovered by astronomer William Herschel on April 27, 1785. It was rediscovered by John Herschel on April 29, 1832 and was listed as NGC 4059.[4] The galaxy is a member of the NGC 4065 Group.[5][6][7][8][9][10][11]

NGC 4070 is also classified as a LINER galaxy.[12]

Physical characteristics

Deep images obtained with the CAFOS instrument at the Calar Alto Observatory reveal that NGC 4070 has some deviation from a perfectly spherical or ellipsoidal shape morphology. This indicates that NGC 4070 has undergone a recent interaction, either with the galaxy 2MASX J12040831+2023280 or with a small knot of material. There also appears to be a faint, broad bridge of luminous matter between NGC 4070 and the neighbouring elliptical galaxy NGC 4066. The two galaxies are separated by a projected distance of 370,000 ly (114 kpc).[13]

SN 2005bl

On April 14, 2005 a type Ia supernova designated as SN 2005bl was discovered in NGC 4070.[13][14][15][16][17]
