The smallest of Jupiter's closest 4 moons is Europa, it has a thick layer of ice over the subsurface ocean that covers the the entire moon. Europa also likely glows, due to radiation from Jupiter's surface, like the color of turquoise! The red spot and Tigers eye are accompanied by just that, a turquoise cab named Europa.
