Curious layman Posted August 24, 2020 Share Posted August 24, 2020 Quote A flood of high-energy radiation and cosmic rays from one or more nearby supernova blasts may have triggered at least one of Earth’s mass extinctions, researchers say, wrecking the planet’s protective ozone layer for an extended period some 359 million years ago https://astronomynow.com/2020/08/24/nearby-supernova-blasts-may-be-culprits-in-at-least-one-mass-extinction/ Link to comment Share on other sites More sharing options...
MigL Posted August 24, 2020 Share Posted August 24, 2020 Article does not mention any candidate supernova that may have been at a distance of 65 light years 350 million years ago. Would be nice to identify the neutron star or Black Hole remains that led to the extinction. And send them the bill for the damage caused. Link to comment Share on other sites More sharing options...
