This line from the article is wrong: > Over nine billion light-years away. With a redshift of z=1.49, the light from SN Refsdal was emitted 9.34 billion years ago, but the proper distance at the current time (a/k/a the co-moving distance) is 14.4 Gly due to the metric expansion of space: https://en.wikipedia.org/wiki/SN_Refsdal https://en.wikipedia.org/wiki/SN_Refsdal Here's the paper announcing the discovery: https://arxiv.org/pdf/1706.10279.pdf https://arxiv.org/pdf/1706.10279.pdf
