Iron 60 isotope
WebAug 22, 2024 · The isotope “did not seem to come from particularly distant stellar explosions, as the iron-60 dust would have dissipated too much throughout the universe if this had been the case.” Also, based on the half-life of iron-60, atoms originating from the formation of Earth would have completely decayed by now. WebAug 21, 2024 · The rare isotope iron-60 is created in massive stellar explosions. Only a very small amount of this isotope reaches the earth from distant stars. Now, a research team with significant involvement from the Technical University of Munich (TUM) has discovered iron-60 in Antarctic snow for the first time. The scientists suggest that the iron isotope […]
