Episode description
Kirk Johnson, director of the Smithsonian Natural History Museum in Washington D.C., paleobotanist, author and science communicator extraordinaire, helps us understand the worst day in the history of Earth: the day an asteroid slammed into the Yucatan Peninsula and wiped out the dinosaurs.
We also break down our song "Chicxulub," a chipper-sounding tune about the site of that asteroid strike.
It's the perfect Halloween episode for the science-minded.
