Titan Is Geologically Active

February 22nd, 2005 | researchmaterial

The Huygens probe that roared through Titan’s atmosphere has provided the strongest evidence yet to suggest Saturn’s giant moon is geologically active beneath its icy surface.

The ratio of carbon isotopes 12C and 13C in Titan’s atmosphere, measured by the probe’s Gas Chromatograph and Mass Spectrometer (GCMS) instrument, indicates that methane is being replenished on the freezing world. Continuing geological activity beneath the surface is thought to be the most likely source…
