Are We Alone?

People have always wondered what life might be like on other worlds. For centuries, our guesses about alien life changed with every new thing we learned about the stars and the planets that circle them. Trace those ideas from ancient thinkers to modern science. Then join today's astrobiologists as they use life here on Earth as their guide, from creatures that thrive in our planet's harshest places to the faraway worlds where life might be hiding. Every program also includes a live tour of the night sky, with the constellations, bright stars, and planets you can spot this season.
Great for: everyone ages 6 and up — anyone who has ever looked up and wondered.
