Title: 
Crescents of Titan and Dione
Explanation: 
What would it be like to see a sky with many moons? Such is the sky above Saturn [ http://www.nineplanets.org/saturn.html ]. When appearing close to each other, moons will show a similar phase [ http://tycho.usno.navy.mil/vphase.html ]. A view with two of the more famous moons of Saturn [ http://antwrp.gsfc.nasa.gov/apod/saturn.html ] in crescent phase [ http://antwrp.gsfc.nasa.gov/apod/ap040829.html ] was captured last month by the robot [ http://robotics.jpl.nasa.gov/groups/rv/homepage.html ] spacecraft Cassini [ http://saturn.jpl.nasa.gov/overview/mission.cfm ] now orbiting Saturn. Titan [ http://en.wikipedia.org/wiki/Titan ], on the lower left, is among the largest moons in the Solar System [ http://seds.lpl.arizona.edu/nineplanets/nineplanets/overview.html ] and is perpetually shrouded in clouds. Recently, the Huygens probe landed on Titan [ http://antwrp.gsfc.nasa.gov/apod/ap050117.html ] and gave humanity its first view of its unusual surface. Dione [ http://www.nineplanets.org/dione.html ], on the upper right, has less than a quarter of Titan [ http://www.solarviews.com/eng/titan.htm ]'s diameter and has no significant atmosphere. Dione [ http://antwrp.gsfc.nasa.gov/apod/ap041201.html ], although appearing smaller, was only half the distance to Titan when the above image [ http://photojournal.jpl.nasa.gov/catalog/PIA06607 ] was taken.
