How long will the new supernova visible in the night sky last?

If you haven’t had a chance to watch the new supernova explode in the night sky, don’t worry: It should last another year, maybe more. And it won’t fade quickly: Scientists expect it will fade slowly until it can no longer be seen in visible light.

The new supernova first exploded on May 19 when supernova hunter Koichi Itagaki of 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.
