Supernova could be seen because its light took different paths . This allowed astronomers to take four images of the ancient star . A massive galaxy cluster warped the light as it travelled to Earth . Einstein predicted this would happen in his theory which explains how objects bend space-time to create what we experience as gravity . Images could help explain dark matter behaviour in nearby cluster . Light from the supernova is expected to reappear weeks .
