Saturn’s moon Titan tagged posts

Despite its uniquely rich inventory of organic molecules, Saturn’s largest moon, Titan, may be able to support only a minuscule amount of biomass, if life exists on the moon, according to a study using bioenergetic modeling.

Titan, Saturn’s largest moon, is a strange, alien world. Covered in rivers and lakes of liquid methane, icy boulders and dunes of soot-like “sand,” its topography has long fascinated scientists and invited speculation on whether lifeforms might lurk beneath the moon’s thick, hazy atmosphere.

Far below the gaseous atmospheric shroud on Saturn’s largest moon, Titan, lies Kraken Mare, a sea of liquid methane. Cornell University astronomers have estimated that sea to be at least 1,000-feet deep near its center — enough room for a potential robotic submarine to explore.

After sifting through data from one of the final Titan flybys of the Cassini mission, the researchers detailed their findings in “The Bathymetry of Moray Sinus at Titan’s Kraken Mare,” which published in the Journal of Geophysical Research.

“The depth and composition of each of Titan’s seas had already been measured, except for Titan’s largest sea, Kraken Mare — which not only has a great name, but also contains ab...

Titan, has features that resemble Earth’s geology, with deep, steep-sided canyons. Using the now-complete Cassini data set, Cornell astronomers have created a new global topographic map of Saturn’s moon Titan that has opened new windows into understanding its liquid flows and terrain.

Creating the map took about a year, according to doctoral student Paul Corlies, first author on “Titan’s Topography and Shape at the End of the Cassini Mission.” The map combines all of the Titan topography data from multiple sources...
