Ammonia-Bearing Compounds Discovered at Surface of Jupiters Moon Europa

Description Advanced analysis of decades-old data from NASAs Galileo spacecraft identifies ammonia-bearing compounds discovered on the surface of Jupiters moon Europa, as shown in this composite image. Zooming in on an area about 250 miles (about 400 kilometers) wide, the black-and-white mosaic to the right is composed of multiple images from Galileos Solid-State Imaging camera. []
