Supernovae on the RISE: Why Dead Stars Wake Up Decades Later

In this episode, we explore the fascinating phenomenon of core-collapse supernovae that refuse to fade away quietly. Years, or even decades, after their initial explosion, some of these stellar deaths experience a surprising "late-time radio rebrightening". We dive into how astronomers are using these delayed radio signals as a time machine to study the final centuries of a massive star's life.
