Show Notes
Billions and billions of years ago, stars in the universe created elements that scattered throughout the galaxies. Until recently, these dust particles from the early universe were frozen in comets. On this program, Dr. Andrew Westphal discussed the StarDust project, the challenges in collecting comet dust and the surprising discoveries made from these samples.
