Appearances of the Refsdal supernova
This video shows the three appearances of the Refsdal supernova in the galaxy cluster MACS J1149.5+2223. Calculations showed that the first image of the supernova appeared in 1998 — an event not observed with a telescope. The second image produced an almost perfect Einstein Cross, which was observed in November 2014 (heic1505). The latest appearance was observed by the NASA/ESA Hubble Space telescope on 11 December 2015, as correctly predicted by seven different models.
The positions of all three events are highlighted in this video with animated supernovae, even though the Einstein Cross event is also visible in the original image.Credit:
