what are we looking for again..?

How many planets exists which might support life? Indeed, what is required for life to exist? How does life start? How does it evolve, and what fabulous creatures can evolution produce? How often do intelligent creatures appear in the giant tapestry of life? It is exactly these questions, and all of them, which are being addressed by the scientists of the Carl Sagan Center for the Study of Life in the Universe.
