Other than Earth , Titan is the only celestial object in the solar arrangement capable of fostering stable liquid on the surface . But now , after years of searching , scientist may have detected waves rippling on its seas — which , if confirmed , would be the first breakthrough of its kind .
The methane , or hydrocarbon , on Titan is basically liquified instinctive accelerator pedal . Though in fluent state , thesemassive bodies of liquidwere thought to be exceptionally calm , go to the trace that no waves exist on the surface of thisSaturnian moonlight .

But back in 2012 and 2013 , NASA ’s Cassini spacecraft captured several glints of sunlight on the surface one of Titan ’s hydrocarbon sea , Punga Mare . look at the images , these unusually burnished reflexion occupy a space no more than four pixels . But according to planetary scientist Jason Barnes , those reflections are a good meter reading of tiny riffle measuring no more than three - quarters of an inch ( 2 centimeter ) high . As Nature Newsreports , he face these finding yesterday ( March 17th ) at the Lunar and Planetary Science Conference :
Calculations of the wave ’ meridian hint they were a shrimpy few cm high . “ Do n’t make your surfriding aeroplane qualification for Titan just yet , ” Barnes told the group discussion .
Knowing how the waves form will help scientist to comfortably empathise the physical atmospheric condition in Titan ’s lakes and sea . A NASA mission marriage proposal , which was beaten by a proposal to revert to Mars , would have sent a probe to float in one of Titan ’s lakes . “ If we sink a lake lander in there , is it run to splat alternatively of splash ? ” asks Barnes .
There is still a opportunity that Cassini is seeing reflections off a wet , solid surface , such as a mudflat , rather than actual waves . Future observations might tell apart the undulation of Punga Mare again , but Barnes says that there is no warrant that Cassini will pass by in the right-hand stead before the last of its mission , a project dip into Saturn in 2017 .
