Merav Opher
Abstract
Did you know that our Sun’s wind generates a kind of protective cocoon that shields our solar system from harmful galactic material, such as radiation? So how did iron-60, a rare radioactive isotope created by exploding stars, end up here on Earth? In this episode, the astronomer Merav Opher talks us through her discovery that explains how iron-60 got into Antarctic ice and tiny shells at the bottom of our oceans—and what this may tell us about some of the key historical moments for planet Earth.
