This week, TED Radio Hour explores one of Earth's most dramatic moments: the day a massive asteroid struck the planet 66 million years ago, wiping out the dinosaurs. Through conversations with scientists and researchers, the episode examines what we can learn from this cataclysmic event and what it reveals about our own planet's fragility.
