Enceladus is one of my favourite moons. The southern region (top in this image) has plumes spewing at up to 2200 km/h. Material from these jets supply Saturn's faint E ring. These plumes contain mostly water vapour, with smaller amounts of nitrogen, carbon dioxide, and hydrocarbons, suggesting the moon has a subsurface ocean of liquid water underneath the icy surface.

What are the blue lines? Is that melted ice in rivers and streams?
