Supernova 2011fe - 27 Aug 11

SN 2011fe is a type la supernova and is located south of the center of M101, which lies some 21 million light-years away. Type Ia supernovae are catastrophic explosions that result from binary stars consisting of a white dwarf star and a companion, in which the dwarf draws material from its companion until reaching a critical point, reigniting nuclear fusion and causing a runaway explosion of the white dwarf that typically outshines the entire host galaxy for some time.
