Saturn's largest moon, Titan, is also shining for attention. Cassini's visual and infrared mapping spectrometer captured Titan glowing both day and
night, powered by emissions from methane and carbon monoxide gases in the moon's extensive, thick atmosphere.
"Not only is Titan putting on a great light show but it is also teaching us more about its dense atmosphere," said Dr. Kevin Baines, science team
member for the visual and infrared mapping spectrometer at JPL. "What is amazing is that the size of this glow or emission of gases is a sixth the
diameter of the planet."
The Sun-illuminated fluorescent glow of methane throughout Titan's upper atmosphere – revealing the atmosphere's immense thickness and extending
more than 700 kilometers (435 miles) above the surface, was expected. However, the nighttime glow, persistently shining over the night side of Titan,
initially surprised scientists.
