Summary
[edit]DescriptionMap of Europa's surface (weic2323c).jpg |
English: This graphic shows a map of Europa’s surface with NIRCam (Near Infrared Camera) in the first panel and compositional maps derived from NIRSpec/IFU (Near Infrared Spectrograph’s Integral Field Unit) data in the following three panels. In the compositional maps, the white pixels correspond to carbon dioxide in the large-scale region of disrupted chaos terrain known as Tara Regio (centre and right), with additional concentrations within portions of the chaos region Powys Regio (left). The second and third panels show evidence of crystalline carbon dioxide, while the fourth panel indicates a complexed and amorphous form of carbon dioxide.Astronomers using Webb have found carbon on the chaos terrain of Tara Regio and Powys Regio. Surface ices in these regions have been disrupted, and there has likely been a relatively recent exchange of material between the subsurface ocean and the icy surface. Carbon, a universal building block for life as we know it, likely originated in Europa’s ocean. The discovery suggests a potentially habitable environment in the salty subsurface ocean of Europa.The NIRSpec/IFU images appear pixelated because Europa is 10 x 10 pixels across in the detector’s field of view.[Image description: Four square panels appear in a horizontal strip. The first features a blue-and-white sphere against a black background. With fuzzy edges, this sphere has darker blue patches in the northern hemisphere and two large white patches in the southern hemisphere.Each of the second, third, and fourth panels has a pixelated, roughly circular image of small, white, blue, or orange squares. In each of these panels, there are slight variations in the arrangement of the coloured squares.] |

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. |
