NGC 4914
Galaxy in the constellation Canes Venatici
From Wikipedia, the free encyclopedia
NGC 4914 is an elliptical galaxy in the constellation of Canes Venatici. Its velocity with respect to the cosmic microwave background is 4,816±22 km/s, which corresponds to a Hubble distance of 231.7 ± 16.3 Mly (71.04 ± 4.99 Mpc).[1] However, three non-redshift measurements give a much closer mean distance of 111.76 ± 21.42 Mly (34.267 ± 6.567 Mpc).[2] It was discovered by German-British astronomer William Herschel on 17 March 1787.[3][4]

NGC 4914 has a possible active galactic nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.[5][6]
