Medical experts agree that cosmic radiation-electrons, positrons, protons, and atomic nuclei hitting Earth from outer space-plays a significant role in limiting human lifespans. Astronomers agree that the vast majority of this life-limiting radiation comes from supernovae, cataclysmic explosions of supergiant stars. Some, but not all, astronomers have suspected that one supernova, the Vela, accounts for nearly all the cosmic ray damage to life on Earth. Others have argued that supernovae remnants scattered throughout our galaxy create a relatively even distribution of cosmic radiation everywhere in the galaxy and certainly throughout the span of Earth's existence.
