Tracking Saturn's Moons

Explanation:
|
These five pairs of Hubble Space Telescope images [ http://www.stsci.ed…] track some of Saturn's moons as they orbit the ringed planet [ http://antwrp.gsfc.…]. A pair of images was taken every 97 minutes on November 21, 1995 with the Wide Field Planetary Camera-2 [ http://www.jpl.nasa…], the normally bright ring system appearing nearly edge-on. In the top pair, the large bright moon Dione [ http://antwrp.gsfc.…] hangs above center while the smaller moons Pandora, Prometheus [ http://antwrp.gsfc.…], and Mimas [ http://antwrp.gsfc.…] (top right image) appear near the planet's disk close to the outer ring. By the second and third pair of images, moons Rhea [ http://antwrp.gsfc.…] and Epimetheus have joined the dance. During the Saturn ring plane crossings [ http://antwrp.gsfc.…], the reduction in light from the edge-on rings provided an opportunity for astronomer's to explore Saturn's complex moon system and search for elusive undiscovered satellites [ http://www.stsci.ed…].
