Ice Cusps on Europa Title Ice Cusps on Europa Title
Explanation:
Europa's icy crust has many unusual features. Pictured above [ http://photojournal…] is part of Europa [ http://www.seds.org…]'s southern hemisphere photographed by the Galileo spacecraft [ http://www.jpl.nasa…] currently orbiting Jupiter [ http://pds.jpl.nasa…]. Europa is one of the largest moons of Jupiter [ http://www.jpl.nasa…], and is thought to have oceans of water [ http://antwrp.gsfc.…] underneath its ice-covered surface. Among many cracks and ridges [ http://antwrp.gsfc.…] appear dark cusp-shaped features running from the lower left toward the upper right. The origin of these features is not known for sure, but their shape is thought to indicate that large portions of Europa's crust [ http://antwrp.gsfc.…] move together, similar to tectonic motion [ http://pubs.usgs.go…] of our Earth's crust [ http://www.windows.…].
