Stereoscopic image of Iapetus, a Saturnian moon, showcasing its unique equatorial ridge. The ridge, approximately 20km wide and 20km high, is a mysterious and unparalleled feature in our solar system, giving the moon a distinctive walnut shape. This image, from a Cassini flyby in 2007, reveals the heavily cratered surface of the ridge. View with red/blue 3D glasses for a more impactful experience.

A striking image of Saturn's moon Iapetus, captured by the Cassini spacecraft. The image showcases Iapetus's unique two-toned surface, with one hemisphere dark and the other light, and its prominent equatorial ridge. The dark material, possibly carbon-rich, is seen coating the eastern part of the moon, covering craters and highlands. A large impact crater is visible in the southern hemisphere. This image offers a fascinating glimpse into the mysteries surrounding this unusual celestial body.
