Web7 ago 2014 · SN 2012Z was seen in January 2012 in the spiral galaxy NGC 1309, located about 110 million light-years from Earth. It is a member of a rare class of supernovae called Type Iax. Type Iax supernovae are less energetic and fainter than their well-known cousins, Type Ia supernovae, which also originate from exploding white dwarfs in binary systems.
