A three-decades-long search may finally have located the hot object left behind by a famous supernova. The light echoes are produced when the initial flash from SN1987a is subsequently reflected off interstellar dust as light travels outward from the event. Computer models that attempt to recreate the conditions just prior to a supernova suggest that there is powerful and rapid mixing inside the star. A team of Japanese scientists has found the first evidence of supernovae in an ice core sample. The gamma rays from nearby supernova ought to have a significant impact on our atmosphere, in particular by producing an excess of nitrogen oxide.
