WASHINGTON: 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. But some — a small fraction — are even brighter than that, 10 to 100 times more luminous. These are called superluminous supernovas.
