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.

Close-up image of Comet Wild 2's surface revealing unusual 100-meter-long spires, unlike any other solar system object. The image shows multiple views of the spires and their shadows, highlighting their unexpected morphology. These features suggest a rigid surface shaped by impacts and sublimation, challenging previous assumptions about cometary composition. The Stardust mission captured this remarkable image.
