Ep. 664: The First Stars

Astronomy Cast Ep. 664: The First Stars by Fraser Cain & Dr. Pamela Gay This show is sponsored by BetterHelp. Visit BetterHelp.com/ASTRONOMY today to get 10% off your first month. The Sun is a third-generation star, polluted with metals from long-dead suns. Astronomers have also discovered second-generation stars, with very low metallicity. But theories suggest there must be a first generation, with stars made from only pure hydrogen and helium. Can we ever find them?
