The Hubble Space Telescope Eyes a Curious Supernova in NGC 2441Supernova SN1995E, discovered in 1995 as its name suggests, is a type Ia supernova. This kind of supernova is found in binary systems, where one star -- a white dwarf -- drags matter from its orbiting companion until it becomes unstable and explodes violently. White dwarf stars all become unbalanced once they reach the same mass, meaning that they all form supernovae with the same intrinsic brightness. Because of this, they are used as standard candles to measure distances in the Universe. [ link to spaceref.com]
