Biggest black-hole outburst ever seen records death throes of a star

Scientists have described a ‘superflare’ from a distant black hole — the most luminous burst of light ever detected from such an object. At its peak, the blaze shone more than 10 trillion times brighter than the Sun and was probably triggered by the black hole’s gravity shredding a star that was at least 30 times as massive as the Sun. The flash also seems to be the farthest ever detected at roughly 10 billion light years away from our Solar System.
