2023年5月26日 · A star in the Pinwheel Galaxy has exploded into a new supernova that was confirmed in May 2023. Here's how to see it for yourself in the night sky.

2023年5月22日 · The new supernova SN 2023ixf, pictured here on May 21st, shines close to a prominent HII region, NGC 5461, in an outer spiral arm of the bright galaxy M101. Discovered on May 19th at magnitude 14.9, it has already brightened to magnitude 11.

SN 2023ixf is a type II-L [7] [8] (core collapse) supernova located in the Pinwheel Galaxy. It was first observed on 19 May 2023 by Kōichi Itagaki and immediately classified as a type II supernova. [2] Initial magnitude at discovery was 14.9. [2]
