Our Celestial Bodies, Ourselves
It's a planet Goldilocks would relish. Scientists are calling Gliese 581C "just right" for supporting life. The newly-discovered planet is not too hot, not too cold ... which means it could harbor liquid water. Have astronomers found Earth's twin? We'll hear how scientists draw on their understanding of our own Earthly body to shed light on planets beyond our solar system. They've even deduced the color of extra-terrestrial trees (it's enough to make you see red!). Also, the contributions of amateur astronomers and the unexpected tragedy that gave rise to modern astronomy.
