NGC 5988

NGC 5988 is a large spiral galaxy in the constellation of Serpens. Its velocity with respect to the cosmic microwave background is 10697 ± 10km/s, which corresponds to a Hubble distance of. However, one non-redshift measurement gives a much larger distance of. It was discovered by American astronomer Lewis Swift on 17 April 1887.
NGC 5988 is a LINER galaxy, i.e. it has a type of nucleus that is defined by its spectral line emission which has weakly ionized or neutral atoms, while the spectral line emission from strongly ionized atoms is relatively weak.
One supernova has been observed in NGC 5988: SN 2023hbv was discovered by ATLAS on 29 April 2023.
