Beschreibung:
In Unmasking Europa, Richard Greenberg tells the story of how he and his team of researchers came to believe that the surface of Europa is in fact a crust so thin and active that it can barely hide an ocean of liquid water below. He shows how this ocean is warmed by the friction of tidal movements in this small moon as it revolves while at the same time orbiting immense Jupiter, and how those tides drive all the activity in evidence on the surface. The implications of this interpretation-which includes the idea that there are active intermittent openings from the liquid ocean to the frozen surface-are immense. The warmth, the chemistry, and the connections from ocean to surface provide the conditions necessary for the existence of life, even at this relatively remote locale in our solar system, far beyond what's normally thought of as its "habitable zone."
