P Autokennzeichen Europa. So if we replaced our moon with europa, it would appear roughly the same size in the sky as our moon does, but brighter — much, much brighter. Astrobiologists— scientists who study the origin, evolution and future of life in the universe — believe europa has abundant water and the right chemical elements, but an energy source on europa has been difficult to confirm.
Europaische Lander from image.slidesharecdn.com Jupiter’s large galilean satellites (io, europa, ganymede, and callisto) likely formed out of leftover material after jupiter condensed from the initial cloud of gas and dust surrounding the sun, early in the history of the solar system. These “extremophile” life forms give scientists clues about how life may be able to survive beneath europa’s ice shell. See full list on solarsystem.nasa.gov
Because of the distance, sunlight is about 25 times fainter at jupiter and europa than at earth.
Liquid water, the appropriate chemical elements, and an energy source. Europa has only a tenuous atmosphere of oxygen, but in 2013, nasa announced that researchers using the hubble space telescope found evidence that europa might be actively venting water into space. See full list on solarsystem.nasa.gov Unlike earth, however, europa’s ocean lies below a shell of ice probably 10 to 15 miles (15 to 25 kilometers) thick and has an estimated depth of 40 to 100 miles (60 to 150 kilometers).
