Indication for supernova produced 60Fe activity on Earth. There are uncertainties relating to the nucleosynthesis yields and the loss of 60Fe during transport, but they do not influence the relative distribution of 60Fe in the crust layers, and therefore our model reproduces the measured relative abundances very well. The remaining supernovae, which formed the Local Bubble, contribute to a smaller extent because they happened at larger distances and longer ago ( 60Fe has a half-life of 2.6 million years 9, 10). The closest occurred 2.3 million years ago at present-day galactic coordinates l = 327°, b = 11°, and the second-closest exploded about 1.5 million years ago at l = 343°, b = 25°, with masses of 9.2 and 8.8 times the solar mass, respectively. The 60Fe signal arises from two supernovae at distances between 90 and 100 parsecs. Here we report calculations of the most probable trajectories and masses of the supernova progenitors, and hence their explosion times and sites. ![]() The Local Bubble of hot, diffuse plasma, in which the Solar System is embedded, originated from 14 to 20 supernovae within a moving group, whose surviving members are now in the Scorpius–Centaurus stellar association 7, 8. ![]() Moreover, peculiarities in the cosmic ray spectrum point to a nearby supernova about two million years ago 6. Recent isotopic analysis is consistent with a core-collapse or electron-capture supernova that occurred 60 to 130 parsecs from the Sun 5.
