The Earth owes its formation to nearby supernovae:

Supernova shockwave -> cosmic ray nucleosynthesis -> radioactive isotopes (26Al) implanted in protosolar disk -> radioactive heating of planetesimals -> drying, volatile evaporation -> terrestrial planets!

A new model indicates that supernova-driven cosmic rays may make rocky, Earth-like planets more common across the galaxy than previously estimated. doi.org/qh63
Supernova immersion model suggests Earth-like planets are more common in the universe
Rocky planets like our Earth may be far more common than previously thought, according to new research published in the journal Science Advances.
