A Europan platypus
A Europan platypus This black-and-white image of Europa's surface was taken by the Stellar Reference Unit aboard Juno during a Sept. 29, 2022, flyby. NASA released the image on May 15, 2024. Icy grooves and ridges dominate the image. In the upper-right corner are dark stains possibly linked to water bubbling up from beneath the surface. At center-right is a section of chaotic terrain that members of the Juno science team refer to as "the Platypus." NASA/JPL-Caltech/SwRI
