Homes for Extraterrestrial Life
Annals of the New York Academy of Sciences, 2001Abstract: Astronomers are now discovering giant planets orbiting other stars like the sun by the dozens.

Searching for Extraterrestrial Life
2004The search for life outside the Earth is currently stuck in the same debate that once surrounded the quest for other planetary systems. Excellent scientists support a spectrum of views ranging from a strong sense that life is such an improbable state of matter that life on Earth is probably all the life there is, through grudging admission that there ...
