Superluminous supernova proclaims the death of a star at cosmic high noon

Ten billion years ago, a massive star ended its life in a brilliant explosion three times as bright as all of the stars in our galaxy, the Milky Way, combined. News of its death, which recently reached Earth, was detected in the Dark Energy Survey being carried out with DECam at the CTIO Blanco telescope (pictured, above right). The supernova is one of the most distant ever discovered and confirmed.
