The explosive supernova deaths of nearby massive stars may have played a significant role in triggering at least two mass extinction events in Earth's history, according to new research.
The story goes that 2.5 million years ago, radiation from a supernova —either in the Scorpius-Centaurus group (460 light-years away) or the Tucana-Horologium group (230 light-years away)—began ...
According to the team's calculations, about one supernova happens every 400 million years within close enough vicinity to Earth that its radiation could impact the atmosphere.
Earth seems to have entered this bubble about 6 million years ago. Passing through the outer wall, where radiation would have been concentrated, could have accounted for the older spike in iron-60 ...
They believe a supernova explosion close to Earth could be to blame for both the late Devonian and Ordovician extinction events, which occurred 372 and 445 million years ago respectively.
