Radio Wave on Saturn's Moon Hints at Hidden Ocean

SleepyHappyDoc writes "The European Space Agency has announced that a mysterious radio wave may indicate the existence of a hidden ocean underneath the surface of Titan. The Cassini-Huygens spaceprobe, which entered Titan's atmosphere over two years ago, collected evidence and information which has led to this potential discovery. This technology may lead to entirely new ways of finding out information about other planets."

A quick googling turns up http://www.nasa.gov/mission_pages/cassini/whycassi ni/cassinif-20070601-02.html [nasa.gov],
an article with considerably more explanation, including that they are investigating through actual simulation whether it could be an artefact of the instrument.

"The results would also be unusual because Titan's dusty surface makes a poor reflector of radio waves"

A potential problem, especially if they were scanning the lower frequencies, is the probable contamination by Saturn's scattered light
