Way back in 1181 AD, astronomers in China and Japan recorded a “guest star” – something that we’d now call a supernova. Over 800 years later, astronomers made a connection between this ancient observation and more recent studies of a very unusual object that goes by the name of “Parker’s Star”.<\/p>\n

Prof Quentin Parker, from University of Hong Kong, explains how he and his team made the link, displacing a previously favoured object. And it seems that this was no common or garden supernova, but an incredibly rare “Type 1ax” supernova.<\/p>\n
