Description

A supergiant star exploded as a supernova in the prominent galaxy M101 in Ursa Major. It’s now bright enough to see in a 4.5-inch telescope!

Superstar supernova hunter Koichi Itagaki discovered the new object, designated SN 2023 ixf, on May 19.7 UT, immediately southwest of the prominent HII region NGC 5461. The pair contrast splendidly in one of the galaxy's outer spiral arms.
