NGC 5716 is a barred spiral galaxy in the constellation of Libra. Its velocity with respect to the cosmic microwave background is 4,384±16 km/s, which corresponds to a Hubble distance of 210.9 ± 14.8 Mly (64.66 ± 4.53 Mpc).[1] However, three non-redshift measurements give a much closer mean distance of 129.70 ± 1.43 Mly (39.767 ± 0.437 Mpc).[2] It was discovered by German-British astronomer William Herschel on 7 May 1787.[3][4]
NGC 5716 has a possible active galactic nucleus, 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.[5][6]
Supernova
One supernova has been observed in NGC 5716:
- SN 2024adxu (Type II, mag. 15.8337) was discovered by the Automatic Learning for the Rapid Classification of Events (ALeRCE) on 12 December 2024.[7]
