The clouds of Venus may harbour alien life. But where else?
NASA's Europa Clipper mission just got the green light - here's what it could achieve.
Varied terrain on Europa.
Whether anything could live in Europa's subsurface ocean depends on what kind of salt it contains. Now scientists have found out.
Once people get there, Mars will be contaminated with Earth life.

Missions including ExoMars, Juno and Rosetta could make some major discoveries in 2016.
An artist’s concept of a plume of water vapour thought to be ejected off the surface of Europa. Could life be beneath?
Jupiter's moon Europa is one of the most enticing objects in our solar system, and a future NASA mission may help reveal whether it is a suitable for life.
What mysteries lie beneath your icy crust, Europa?
NASA has now formally started to pack its bags for the next big discovery mission, this time heading to Jupiter’s icy moon Europa. Last month NASA announced the instruments that will fly on this trip and…
With geysers bursting through an icy crust, Enceladus is a tiny moon with a big personality.

Saturn's tiny moon Enceladus joins Europa and Mars as possible locations for life beyond Earth.
The prize, Europa, a watery world.
The icy moon Europa is perhaps the most tantalising destination in our solar system. Scientists have been trying for years to kickstart a mission to Jupiter’s most enigmatic moon, with very Earth-like…
