Pesquisadores da Universidade do Havai descobriram que Titan, a maior lua de Saturno, possui uma crosta de clatrato de metano com espessura entre 2 e 9 quilômetros, o que pode explicar fenômenos na superfície e atmosfera do satélite e abrir novas possibilidades para futuras missões.

Snapshots of Titan North Polar Cloud

This series of false-color images obtained by NASA Cassini spacecraft shows the dissolving cloud cover over the north pole of Saturn moon Titan, allowing scientists to see the underlying northern lakes and seas, including Kraken Mare.

Lake-like but Different

This mosaic of image swaths from Cassini’s Titan Radar Mapper, taken with the synthetic-aperture radar SAR, features a large dark region several hundred kilometers across that differs in several significant ways from potential lakes observed on Titan.

Fenzal and Aztlan

Although hidden from human eyes, NASA Cassini spacecraft can spot these dark features on the surface of Titan dubbed Fensal and Aztlan. The dark features are believed to be vast dunes of particles that precipitated out of Titan atmosphere.

Titan Temperature Lag Maps

This sequence of maps shows varying surface temperatures on Saturn moon Titan at two-year intervals, from 2004 to 2016. The measurements were made by the Composite Infrared Spectrometer CIRS instrument on NASA Cassini spacecraft. The maps show thermal infrared radiation (heat) coming from Titan's surface at a wavel...
