The death of a star is one of the most dramatic and violent events in space -- and astronomers had an unprecedented front-row seat to the explosive end of a stellar giant.
Ground-based telescopes provided the first real-time look at the death throes of a red supergiant star. While these aren't the brightest or most massive stars, they are the largest in terms of volume. Hubble spies the culprit behind Betelgeuse star's dimming. And it may be happening againOne popular red supergiant star is Betelgeuse, which has captured interest due to its irregular dimming. While it was predicted that Betelgeuse may go supernova, it's still around.
