NGC 3074 is a barred spiral galaxy in the constellation of Leo. Its velocity with respect to the cosmic microwave background is 5,395±18 km/s, which corresponds to a Hubble distance of 259.5 ± 18.2 Mly (79.57 ± 5.58 Mpc).[1] It was discovered by German-British astronomer William Herschel on 28 March 1786.[2][3]
NGC 3074 is an active galaxy nucleus candidate, 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.[4]
