Summary
DescriptionEuropa (NIRCam image, cropped) (weic2323b).jpg |
English: 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.] |

JPEG file comment | For as long as humans have gazed into the night sky, we have wondered about life beyond the Earth. Scientists now know that several places in our solar system might have conditions suitable for life. One of these is Jupiter’s moon Europa, a fascinating world with a salty, subsurface ocean of liquid water—possibly twice as much as in all of Earth’s oceans combined. However, scientists had not confirmed if Europa’s ocean contained biologically essential chemicals, particularly carbon, the universal building block for life as we know it. Now, using the James Webb Space Telescope, astronomers have found carbon on Europa’s surface, which likely originated in this ocean. The discovery signals a potentially habitable environment in the ocean of Europa. |
