11 October 2012, 05:54 PM ET
in 2005, the Huygens Probe took about 10 seconds to finally come to a rest on the surface of the Saturn Moon. 'Fluffy' dust-like material shot up off the surface for about 4 seconds after landing.
05 October 2012, 12:23 PM ET
Many astronomers and astrobiologists think that Titan – with its thick atmosphere of methane and liquid hydrocarbon lakes – could harbor some form of life. 50% larger than Earth’s moon and 80% more massive, Titan is an analog to the early Earth.

28 September 2012, 03:12 PM ET
Locked beneath the icy surface of Europa is perhaps as much water as in all of Earth's oceans and lakes. But could there be life in the salty underground global sea?
