If you haven't had the chance to observe the new supernova exploding in the night sky, don't worry — it should be around for another year, maybe more. And it won't vanish quickly — scientists expect it will slowly fade away until it can no longer be seen in visible light.
The new supernova first burst into view on May 19 when supernova hunter Koichi Itagaki from Yamagata, Japan spotted a new bright spot in the Pinwheel Galaxy. The supernova was confirmed the following day by the Zwicky Transient Facility (ZTF) in California.
