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.
An ultraviolet image taken from NASA's Solar Dynamics Observatory spacecraft shows Venus at the top left of the sun.
Venus transiting in front of the Sun.
The blue color of this image is used to show contrasts in cloud patterns. This image was taken with a violet filter.
The Magellan probe orbited Venus from 1990 to 1994 and peered through the clouds: this image was created by emitting and re-detecting cloud-penetrating radar.
