One day just over a thousand years ago something unprecedented appeared in the sky. The year was 1054 and the Chinese and Arabic astronomers who observed the phenomenon noted a brightness that increased with remarkable speed. This was the result of something we now know to be caused by the massive explosion of a star with a mass roughly ten times that of the sun itself – a phenomenon known as a supernova.
