,Water—Where Does It Come from?,uced later in the stellar interiors, maybe in this context extremely massive stars (so called population III stars) played an important role. Only after their explosion to supernovae, these oxygen atoms were set free into interstellar space where they could combine with hydrogen to form water under the appropriate conditions.

Life and Water,ow it from Earth is discussed here. Life as we know it from Earth is based on liquid water and carbon molecules. Life can also exist under extreme conditions. Several examples of extremophiles are given. Life cannot exist without a constant supply of energy. On Earth, this energy comes from the Sun.

Satellites of Planets in the Solar System,ery promising candidates for hosting an ocean of salty liquid water beneath a thick ice shield. The existence of a subsurface ocean on some satellites of Saturn like Titan is also reviewed. The latest results from the Cassini mission to Saturn concerning Titan and Enceladus are shown.

Water on Small Solar System Bodies,s might have been supplied by the impact of these objects in the heavy bombardment phase of the early solar system evolution. Water on small solar system bodies such as asteroids, comets, objects in the Kuiper belt and Oort cloud seems to be quite common. Its presence and the detection is reviewed.
