  • A 25-year hunt for a bright spot in the sky first seen almost six centuries ago has traced it to a stellar explosion--and answered a long-standing question about such cosmic events. On 11 March 1437, royal astronomers in Korea noticed that "a guest star began to be seen between the second and third stars of Wei"-- Wei being a group of nine stars in the constellation Scorpius. Now, Michael Shara at the American Museum of Natural History in New York has discovered its origin: a kind of explosion called a classical nova.
