Another World Awaits "The interest of such planets is at least double, for Planetology and Exobiology. They would be a kind of objects we have not in the Solar System and significantly extend the field of Planetology. The search for a form of life similar to that which has developed on Earth would open a new field in Exobiology because the conditions of the environment would be quite different from the terrestrial ones. The minerals necessary to living bodies (P, S, Fe, Mg, Na, K…) could be brought to the surface by micro-meteorites or found in the ocean as dissolved species. It could even tell us something about origin of life on Earth e.g. by excluding an origin from black smokers at the silicate/ocean interface because on Ocean-Planets, liquid water and silicates would be separated by thousands of kilometres of ice" (p. 2).
