SUMMARY
Betelgeuse, a red supergiant star located approximately 400 light-years away, is on the verge of going supernova, potentially classified as a type II supernova. Observations indicate that Betelgeuse is shrinking, which suggests it may have already undergone core collapse, although the explosion may not be visible from Earth yet. The star's behavior, characterized by cycles of shrinkage and expansion, indicates that it could have exploded years ago without our knowledge. This phenomenon raises intriguing questions about the timing and visibility of supernova events.
