Scientists unveiled the first global geological map of Saturn’s moon Titan, including vast plains and dunes of frozen organic material and lakes of liquid methane.
The map was based on radar, infrared and other data collected by Nasa’s Cassini spacecraft.
Titan is the only solar system object other than Earth which has stable liquids on the surface.
Titan (diameter 5,150km), is the solar system’s second-biggest moon, behind Jupiter’s Ganymede.
