NGC 2595
Galaxy in the constellation Cancer
From Wikipedia, the free encyclopedia
NGC 2595 is a spiral galaxy in the constellation of Cancer. Its velocity with respect to the cosmic microwave background is 4,576±17 km/s, which corresponds to a Hubble distance of 220.1 ± 15.4 Mly (67.49 ± 4.73 Mpc).[1] This is in good agreement with 24 non-redshift measurements which give a distance of 224.15 ± 11.85 Mly (68.725 ± 3.632 Mpc).[2] It was discovered by German-British astronomer William Herschel on 11 January 1787.[3][4]

Supernova
One supernova has been observed in NGC 2595: SN 1999aa (Type Ia-pec, mag. 15.5) was discovered by Ron Arbour,[6] and independently by the Beijing Astronomical Observatory, on 11 February 1999, and by Reiki Kushida on 13 February 1999.[7][8] This supernova was overluminous and exhibited one of the most slowly declining brightnesses known.[9]
