The image covers a section of Europa's surfacemeasuring approximately 150 km by 200 km, dotted with a network of thin grooves and double ridges (pairs of long parallel lines indicating elevations in the ice). The white dots in the image are signatures of penetrating high-energy particles from the strong radiation environment around the moon.
The black and white image was taken at a distanceabout 412 km, resolution - from 256 to 340 meters per pixel. During the photograph, Juno was traveling at a speed of about 24 km/s over a part of Europa's surface that was dimly illuminated at night by the "Jupiter glow" - sunlight reflecting off the gas giant's cloud tops.
