Enceladus and Titan

Pictures of Saturn’s moon Enceladus (left) taken by NASA satellite Cassini are released Monday. With a diameter of 500 kilometers, Enceladus creates colorful patterns with gas and ice generated by frictional heat with Saturn’s other moons and pouring out at the rate of 2,100 kilometers per hour. Titan, Saturn`s biggest moon, looks blue since it is covered by nitrogen and methane. Cassini has transmitted pictures of Saturn and its moons since entering the planet`s orbit in 2004.
