Europa: the "Agenor Linea"

Caption NASA originale:"This bright white swath cutting across the surface of icy Jovian moon Europa is known as "Agenor Linea". In all about 1000 Km long and 5 Km wide, only a section is pictured here as part of a combined color and black and white Galileo's images. Most linear features on Europa are dark in color but Agenor Linea is uniquely bright for unknown reasons. Also unknown is the origin of the reddish material along the sides. While these and other details of Europa's surface formations remain mysterious, the general results of Galileo's exploration of Europa have supported the idea that an ocean of liquid water lies beneath the cracked and frozen crust. An extraterrestrial liquid ocean holds out the tantalizing possibility of life". Curioso: alla NASA sono davvero incapaci di fare commenti equilibrati alle immagini che loro stessi propongono. Parlano di "Tantalizing possibility of life" sotto il ghiaccio di Europa, ma sono incapaci di dire che su Marte, forse, esiste qualche forma di vita...
