NGC 5090 And NGC 5091
NGC 5090 and NGC 5091 are a set of galaxies approximately 160 million light-years (50 million parsecs) away in the constellation Centaurus. They are in the process of colliding and merging with some evidence of tidal disruption of NGC 5091.
NGC 5090 is an elliptical galaxy while NGC 5091 is a barred spiral galaxy. The radial velocity of the nucleus of NGC 5090 has been measured at 3,185 km/s (1,979 mi/s), while NGC 5091 has a radial velocity of 3,429 km/s (2,131 mi/s). NGC 5090 is associated with the strong, double radio source PKS 1318-43.
One supernova has been observed in NGC 5090: SN 1981C (type unknown, mag. 14.5) was discovered by José Maza on 2 March 1981.
