A newly built International Liquid Mirror Telescope (ILMT) in India has identified its first supernova—designated SN 2023af. The finding, reported November 8 on the pre-print server arXiv, proves that ILMT may be capable ...
A newly discovered nearby supernova whose star ejected up to a full solar mass of material in the year prior to its explosion is challenging the standard theory of stellar evolution. The new observations are giving astronomers ...
