In 2005 the robotic Huygens probe landed on Titan, Saturn’s enigmatic moon, and sent back the first ever images from beneath Titan’s thick cloud layers. This artist’s impression is based on those images. In the foreground, sits the car-sized lander that sent back images for more than 90 minutes before running out of battery power. The parachute that slowed Huygen’s re-entry is seen in the background, still attached to the lander. Smooth stones, possibly containing water-ice, are strewn about the landscape. Analyses of Huygen’s images and data show that Titan’s surface today has intriguing similarities to the surface of the early Earth. Image Credit: ESA
