NGC 5936

NGC 5936 is a barred spiral galaxy in the constellation of Serpens. Its velocity with respect to the cosmic microwave background is 4131 ± 11 km/s, which corresponds to a Hubble distance of 60.93 ± 4.27 Mpc (~199 million light-years).^[1] It was discovered by German-British astronomer William Herschel on 12 April 1784.^[2]
