NGC 3836 is a peculiar spiral galaxy in the constellation of Crater. Its velocity with respect to the cosmic microwave background is 4,022±26 km/s, which corresponds to a Hubble distance of 193.5 ± 13.6 Mly (59.32 ± 4.17 Mpc).[1] It was discovered by German astronomer Wilhelm Tempel on 29 April 1877.[2]
NGC 3836 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.[3]
