Animation showing how Hubble spotted four images of the same supernova
Astronomers using the NASA/ESA Hubble Space Telescope have, for the first time, spotted four images of a distant exploding star. The images are arranged in a cross-shaped pattern by the powerful gravity of a foreground galaxy embedded in a m***ive cluster of galaxies. The supernova discovery paper will appear on 6 March 2015 in a special issue of Science celebrating the centenary of Albert Einstein’s theory of general relativity.
Whilst looking closely at a m***ive elliptical galaxy and its ***ociated galaxy cluster MACS J1149+2223 — whose light took over 5 billion years to reach us— astronomers have spotted a strange and rare sight.
