New Supernova Lights up M82 — “The Cigar Galaxy”.
There’s one supernova every second somwhere in the Universe. They are among the most powerful events in the universe, releasing so much energy that a single outburst can outshine an entire galaxy. A new supernova, dubbed SN 2014J, is of a particular kind known as a Type Ia. This type of supernova results in the complete destruction of a white dwarf star-the small, dense, aged remnant of a typical star like our sun.
