It's worth noting that when scientists talk about how it's "about to go" supernova, they are saying within the next 10,000 to 100,000 years at the very least.
Dr Becky covered that paper in her video, where the new paper was suggesting within several decades to a hundred or so years. However that is also all based on simulations from observations.
I was going to recommend her recent video that covered the subject. A great explanation of exactly what happens to the fusion process in a star as it runs out of fuel, and what scientists are looking for to signal those changes.
Link to that video for those interested: https://youtu.be/3QgLwpuDGhI
!RemindMe
It's possible it already did. Takes a while for a us to see it
Over 600 years, but that's still miniscule compared to the lifetime of the star.
