Explanation:

Voyager spacecraft [ http://nssdc.gsfc.n…] images of Europa's surface [ http://seds.lpl.ari…], like the one above, are suggestive of sea ice on Earth [ http://antwrp.gsfc.…]. The criss-crossing dark streaks may indeed be cracks in its ice-covered surface caused by Jupiter's tidal stresses accompanied by the freezing and expansion of an underlying layer of water [ http://antwrp.gsfc.…]. This tantalizing prospect of oceans of liquid water [ http://antwrp.gsfc.…] beneath its frozen surface has helped make the smallest of the Galilean [ http://galileo.imss…] moon's of Jupiter a planned focus of the Galileo spacecraft's ongoing mission to explore the Jovian system. New Europa images and results [ http://newproducts.…] from the Galileo mission were released today revealing [ ftp://ftp.hq.nasa.g…] details which further suggest that Europa's icy surface was once - and may still be - supported on slush or liquid water.
