ARECIBO, P.R. -- The smog-shrouded atmosphere of Titan, Saturn's largest moon, has been parted by Earth-based radar to reveal the first evidence of liquid hydrocarbon lakes on its surface. The observations are reported by a Cornell University-led astronomy team working with the world's largest radio/radar telescope at the National Science Foundation's (NSF) Arecibo Observatory. ... The piggybacking Huygens probe is scheduled to plunge into the hazy Titan atmosphere and land on the moon's surface. ...
