In January a new supernova was spotted in the M82 galaxy – dubbed SN2014J is one of the closest supernovae to occur in the last couple of decades while active observation has been in effect. It is though to be a type Ia Supernova, formed when one of a pair of stars collapses into a white dwarf star which then accumulates material from its partner until enough materials has passed to the dwarf star for it to collapse in on itself – SN2014J is the closest type Ia supernova to occur since SN1972E whose observation forms much of the basis of understanding of type Ia supernovae.
