This artist's impression shows what NASA's HAVOC plan for a human colony on Venus would look like over the clouds of the planet.
Venus has a surface temperature hot enough to melt lead and its atmospheric pressure is the equivalent of diving a mile underwater. This artist's impression shows a lighting storm seen from the planet's atmosphere.
The Galileo spacecraft took this picture of cloudy Venus. The planet is similar to Earth in size and mass - and so is sometimes referred to as Earth's sister planet - but it has a quite different climate.
The planet is constantly shrouded in thick clouds and a runaway greenhouse effect is ongoing.
