The Biggest-Ever Supernova, Debunked!

The video discusses the reevaluation of a record-breaking supernova, which was found to be a tidal disruption event caused by a supermassive black hole. It also covers the study of weather on exoplanet HAT-P-7 b, revealing high-speed winds and cloud formation due to its tidally locked nature. The video concludes with a promotion for SciShow Space and NerdCon.
