Life Beyond Earth
Do you think it’s possible that aliens exist, as Gary thinks in "Future Tense?" This PBS site explores whether life exists elsewhere in the universe. Click on Are We Alone? and Is Anybody Listening? to learn about the search for intelligent life. What would you say if we did manage to make contact? Write a letter to an alien telling about life on Earth and asking questions about the alien’s world.
