Europa Rotating Title Europa Rotating Title
Explanation:
Evidence has been mounting that beneath the vast planes of ice that cover Europa [ http://antwrp.gsfc.…] lies water -- liquid oceans that might be home to alien life [ http://www.sciam.co…]. The smallest of Jupiter [ http://www.seds.org…]'s Galilean Moons [ http://solarviews.c…] (which include Io [ http://www.seds.org…], Ganymede [ http://www.seds.org…], and Callisto [ http://www.seds.org…]), Europa's deep interior is composed of mostly of silicate rock [ http://windows.arc.…]. Upon close inspection, many surface cracks [ http://antwrp.gsfc.…] stop abruptly only to continue on somewhere else -- indicating surface plates that might be sliding [ http://antwrp.gsfc.…]. The above time-lapse sequence [ http://www.solarvie…] is a composite of images taken during the Voyager spacecraft [ http://vraptor.jpl.…] flyby of the moon twenty years ago. Not all regions are resolved in high detail. The movie shows Europa [ http://www.seds.org…] during a complete rotation, which corresponds to a complete revolution around Jupiter [ http://www.jpl.nasa…] since Europa [ http://cass.jsc.nas…] always keeps the same face toward the giant planet. The cause of many of the surface colors on Europa [ http://www.solarvie…] also remains a topic of research [ http://antwrp.gsfc.…http://adsabs.harva…].
