Even at the Solar System's current location, some scientists have speculated that recent supernovae may have adversely affected life in the last 35,000 years, by flinging pieces of expelled stellar core towards the Sun, as radioactive dust grains and larger, comet-like bodies.
Til og med i Solsystemets nuværende position har man spekuleret at nylige supernovaer kan have påvirket livet negativt under de seneste 35.000 år gennem at slynge dele af stjerner mod Solen i form af radioaktivt stof og større kometlignende himmellegemer.
