Star has exploded in ‘fatal’ supernovae multiple times since 1954 – and is the first star astronomers have witnessed doing soAstronomers have spotted a “zombie star” that refused to die when massive explosions that are normally considered fatal rocked the heavenly body. It is the first time astronomers have seen the same star explode over and over. The first type of supernova happens when a white dwarf star made from carbon and oxygen attracts material from another star that it orbits. WilkinsonThe astronomers ruled out the most common supernova theories, but found one that explained some of the star’s odd behaviour. “For now the supernova offers astronomers their greatest thrill: something they do not understand,” he said.
