For the first time a star has been observed in real-time as it goes supernova – a mind bogglingly powerful explosion as the star ends its life, the resulting cosmic eruption briefly outshining an entire galaxy. UK scientists, in collaboration with international colleagues, used NASA's Swift satellite and a combination of orbiting and ground-based observatories to catch a supernova in the act of exploding. The results, including an associated and intriguing Gamma Ray Burst [GRB], appear in 31 August issue of Nature.
