Artist’s conception of SN 2023ixf. One of the nearest Type II supernovae in a decade and among the brightest to date, SN 2023ixf is a young supernova, discovered earlier this year by amateur astronomer Kōichi Itagaki of Yamagata, Japan. This artist’s conception shows the bright explosion of SN 2023ixf, which occurred after an unexpected amount of mass loss unlike anything astronomers have seen before. Credit: Melissa Weiss/CfA
