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.
