(Phys.org)—SN Refsdal is a peculiar supernova visible within the field of the galaxy cluster MACS J1149+2223. Discovered in November 2014 using the Hubble Space Telescope, this supernova is the first that was seen multiple times thanks to gravitational lensing. Now, an international team of astronomers has published a paper on Jan. 15 summarizing one year of Hubble observations of SN Refsdal. The research is available online on the arXiv pre-print server.
