Description
What can a 66-million-year-old impact crater reveal about the past and future of life on Earth? Dr. Sean Gulick explores the science behind one of the most dramatic events in Earth’s history, the asteroid impact that ended the age of dinosaurs. From discovering a giant crater in Mexico to drilling deep into the Earth to link this impact to the mass extinction, Dr. Gulick unpacks the explosive chain of events that wiped out 75 percent of life on the planet. Current research is studying how meteorite impacts shape planets, create new ecosystems and may even help life begin on Earth and on other worlds.
