Earth may have spent the last 33,000 years drifting through what’s left of huge supernova explosions, scientists have theorized, going deep into the ocean for evidence of one of the most mysterious known substances. Samples of iron-60, a radioactive isotope generated by supernovas, have been discovered on the ocean floor, a faint reminder of dying stars.
Iron-60’s radioactivity makes it a natural time-keeper. Since it decays completely within 15 million years, scientists can be confident that …
