Appearances of the Refsdal supernova

Δημοσιεύτηκε στις 16 Δεκ 2015
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.
