The Cassini spacecraft continues its journey around Saturn. It was launched in 1997 and reached the ringed planet for a scheduled 4-month mission but it's still alive and kicking today. Here are some of its best images over the past few months.
In this amazing image are the moons of Saturn most likely to contain life. Enceladus contains ice-water geysers indicate that there might be subsurface water which could contain organisms. In the background is Titan, the only moon in the solar system with an atmosphere.
