Europa (NIRCam image)

Webb’s NIRCam (Near Infrared Camera) captured this picture of the surface of Jupiter’s moon Europa. Webb identified carbon dioxide on the icy surface of Europa that likely originated in the moon’s subsurface ocean. This discovery has important implications for the potential habitability of Europa’s ocean. The moon appears mostly blue because it is brighter at shorter infrared wavelengths. The white features correspond with the chaos terrain Powys Regio (left) and Tara Regio (centre and right), which show enhanced carbon dioxide ice on the surface.

[Image description: A blue-and-white sphere against a black background is somewhat reminiscent of the famous “Blue Marble” picture of Earth from space. With fuzzy, diffuse edges, this sphere features darker blue patches in most of the northern hemisphere facing the viewer. One, large, crescent-shaped, white patch extends along the left side of the southern hemisphere facing the viewer, and a larger, blobby, white patch covers the middle latitudes of the right side of the southern hemisphere. Lighter blue regions border these white patches in the south.]
