Explicatie: (Edit) This is the closest photograph ever taken of Europa. Last December, NASA's spacecraft Galileo swept past the Jovian moon and took photographs which were released yesterday. Speculation that life-bearing oceans exist beneath Europa's surface caused NASA to put Galileo on orbits that approach Europa. The above photograph shows new details on Europa's surface, indicating that much of Europa as strewn with bumps and hills of ice laced with long fractures. Dark circular features may be impact craters.
