NGC 2397 is a classic spiral galaxy, located in the Volans constellation. It is about 60 million light-years from Earth.[2] The nucleus consists of older yellow and red stars; more recent stars have formed within the outer blue spiral arms, which also feature protrusions of dust.[3]
John Herschel discovered the galaxy on February 21, 1835.[4] In March 2006, a star in the galaxy, SN 2006bc, was spotted in the late stages of supernova.[2] Astronomers at Queen's University Belfast, who have been studying supernovas to find out what sort of stars explode, worked through previously captured images of the galaxy and found one of when the star exploded, one of only six ever collected.[5]
