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 . The result was a picture that showed how far away this supernova had been from us, and what kind of explosion we would expect if one exploded in our own Galaxy.
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 the next few years .
