Near-Earth Supernova Explosions: Evidence, Implications, and Opportunities
Abstract
Geological and lunar evidence of radioactive 60Fe implies that at least one supernova exploded within 100 pc of Earth within the last few Myr. The unique information provided by 60Fe to assess nearby supernovae make now a compelling time for the astronomy community to advocate for supporting multi-disciplinary, cross-cutting research programs.
