19: The Hitchhiker's Guide to the Galaxy
How did the ingredients of life arrive on Earth?
Today, we look at how asteroids brought organic material from the depths of space to Earth's surface. On the way, we'll run into an old friend from Episode 4, meet an ancient Greek astronomer, and search for aliens hidden in Antarctic ice.
Extra credit: Eat something with glutamic acid in it- meat, mushrooms, or soy sauce. Extra extra credit if you can have all three at once.
