Chaos terrain and Phaidra Linea, Europa (11ESREGMAP01)
Chaos terrain on Europa, in the upper right of this image, is a place where the bright, icy crust has been broken and deformed. It represents some of the most recent geologic activity on Europa. In the southern part of the image is a smooth, gray band provisionally named Phaidra Linea, where the crust has pulled apart, separating preexisting geologic features, much like a mid-ocean ridge on Earth. The image covers an area roughly 350 kilometers square near Europa's equator.
