Callisto Enhanced Title Callisto Enhanced Title
Explanation:
Callisto [ http://antwrp.gsfc.…] is half rock and half ice. This moon of Jupiter [ http://www.hawastso…] is approximately the size of the planet Mercury [ http://www.seds.org…], making it the third largest moon in the Solar System [ http://antwrp.gsfc.…], after Ganymede [ http://www.jpl.nasa…] and Titan [ http://www.seds.org…]. Callisto [ http://www.seds.org…]'s icy surface is billions of years old, lacks any sign of volcanic activity [ http://antwrp.gsfc.…], and is densely covered with rifts and craters. These features are particularly apparent in this contrast-enhanced image [ http://photojournal…] taken by the Galileo spacecraft [ http://www.jpl.nasa…], and released last week. Visible near the image center is Valhalla [ http://www-a.jpl.na…], one of the largest impact craters in the Solar System, measuring about 4,000 kilometers across. The rings and size of Valhalla [ http://www.hawastso…] make its appearance similar to the Caloris Impact Basin [ http://antwrp.gsfc.…] on Mercury.
