The new worlds

de Fabienne Casoli, Thérèse Encrenaz

"There is a lot to be learned from studying extrasolar planets. However, the most tantalizing data is the possible discovery of Earthlike extrasolar planet, with a mass comparable to that of Earth, located at the right distance from its star to host liquid water - in other words, a place where life might have evolved or still could evolve."--book jacket.
