Lenticulae on Europa
The round, reddish spots in this image, each about 10 kilometers (6 miles) across, are named "lenticulae" (Latin for "freckles"). Generally, reddish features on Europa appear to be younger than the grayer or bluer features. Round features on planets that do not have an obvious impact origin are most often interpreted to be the result of upwelling of hot, less dense material to the surface.
