NASA Spacecraft Watches Summer Clouds on Saturn’s Moon
Added Nov 18, 2016 | Rate View top rated
NASA's Cassini spacecraft watched clouds of methane moving across the far northern regions of Saturn's largest moon, Titan, on October 29­­­­ and 30, 2016. Several sets of clouds develop, move over the surface, and fade during the course of this movie sequence, which spans 11 hours - with one frame taken every 20 minutes. Time-lapse movies like this allow scientists to observe the dynamics of clouds as they develop, move over the surface and fade. A time-lapse movie can also help to distinguish between noise in images (for example from cosmic rays hitting the detector) and faint clouds or fog. The movie was acquired using the Cassini narrow-angle camera using infrared filters to make the surface and tropospheric methane clouds visible.
