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]

NGC 5936 is listed as a luminous infrared galaxy (LIRG),^[1] and as a field galaxy, i.e. one that does not belong to a larger galaxy group or cluster and hence is gravitationally alone.^[3]

Two supernovae have been observed in NGC 5936:

SN 2013dh (type Ia, mag 18) was discovered by the Lick Observatory Supernova Search (LOSS) on 12 June 2013.^[4]^[5]
