Dedicated amateur discovers supernova in remote galaxy

Astronomy is increasingly becoming an online affair. Recent discoveries of interstellar Comet 3I/ATLAS and R2 SWAN have highlighted this fact, when both were first discussed on message boards and verified via remote telescopes before confirmation. Another recent find also shows what's possible, as devoted amateur astronomer Filipp Romanov has accomplished an amazing feat, and discovered a supernova in a remote galaxy.
