The Titanian Volcano (1)

Caption NASA originale:"On Oct. 26, 2004, the Cassini spacecraft flew over Titan at less than 1.200 Km at closest approach. Cassini acquired several infrared images with spatial resolution ranging from a few tens of Km to 2 Km per pixel. The Visual and Infrared Mapping Spectrometer took images from visible wavelengths to the 5,1 micron wvlgts. This figure shows the mosaic obtained at the 2,03 micron wvlgt - observations are centered on the hemisphere of Titan that points away from Saturn. The left (inset) HR image is 30 Km per pixel. It shows the site where the ESA's Huygens probe successfully landed on Jan. 14, 2005. The right inset shows a circular feature that scientists think is a volcano, which may be responsible for replenishing Titan's methane atmosphere".
