Scientifically, how do we know there was a super nova in 4000 BC? Is there still star remnants to observe? How do we trace that back to a date?

- Finnucane 9y agoFrom the article: "They settled on Supernova HB9, a star that exploded around 4,600BC." It is possible from observed supernova remnants to have a pretty good estimate of when the star exploded, esp. when it is relatively 'recent', astronomically speaking.
