b. Enceladus
c. Tethys
d. Dione
ANSWER: Titan
NASA’s Cassini spacecraft has discovered a new could of frozen compounds in the stratosphere of the largest moon of Saturn, Titan. The cloud system has been found at the stratosphere’s lower part at an altitude of 200 km. It detected by Cassini's infrared instrument - the Composite Infrared Spectrometer/ CIRS - which obtains profiles of the atmosphere at invisible thermal wavelengths. The cloud has a low density like Earth’s fog and has a flat top. Each Titan season lasts for 7.5 earth years and the south pole of the moon will be covered by winter when the mission ends in 2017. Ice clouds at Titan's pole don't form in the same way as Earth's familiar rain clouds.
