This time-lapse sequence of Saturn’s giant moon Titan is composed of frames taken every 20 minutes over an 11-hour period. It was made with images captured by NASA’s Cassini spacecraft, and it shows long bands of streaked cloud forming and fading in Titan’s mid-latitudes. Calculations indicate they were travelling at a sedate pace: some 14-22 mph (23-35 km/h). Sequences like this allow atmospheric scientists to study the dynamics of Titan’s clouds, and how they are linked to its climate and seasons. More cloud development had been predicted in the moon’s Northern Hemisphere summer than Cassini actually observed, suggesting there’s still much to learn about the atmosphere of Titan.
