These observations of NASA's Voyager and Galileo's Near Infrared Mapping Spectrometer shows the interception of two lineas or fractures on the Northern hemisphere of Europa.

This observation taken by the Near Infrared Mapping Spectrometer (NIMS) at 0.7 microns (left image) shows the interception of two lineas or fractures on the Northern hemisphere of Europa. A comparison Voyager visible-light image is shown at the right. The NIMS image at 4 km resolution shows dark hydrated material concentrated in the linea structures (dark lines in the Voyager and NIMS images). Note the dark spot at the lower left of the upper linea; its spectra matches the hydrated spectra of the lineas.

The Jet Propulsion Laboratory, Pasadena, CA manages the mission for NASA's Office of Space Science, Washington, DC.
