Radioactive Iron Rain!

The video explores atmospheric science, focusing on gravity waves in Pluto's atmosphere, distinct from gravitational waves. It explains how gravity waves form and their presence on Earth and Mars. The video also discusses radioactive elements from supernovae found in Earth's crust, suggesting past supernovae may have influenced Earth's climate. Recent findings indicate Iron 60 continues to rain down on Earth, though in negligible amounts. The episode concludes with acknowledgments to SciShow patrons and mentions a project on interstellar travel.
