WASHINGTON, March 11 (Reuters) - A supernova - the explosion marking the end of a massive star's life - is one of the brightest cosmic events, usually about a billion times more luminous than the sun.

A supernova is one of the most powerful events that can happen in the Universe - we are talking, after all, about a star exploding – and because of that, they have always been actively researched by ...
