Geoffrey A. Landis of NASA's Glenn Research Center has summarized the perceived difficulties in colonizing Venus as being merely from the assumption that a colony would need to be based on the surface of a planet: However, viewed in a different way, the problem with Venus is merely that the ground level is too far below the one atmosphere level.
Nevertheless, life need not originate during this stage of stellar evolution for it to be detected. Once the star becomes a red giant, and the habitable zone extends outward, the icy surface would melt, forming a temporary atmosphere that can be searched for signs of life that may have been thriving before the start of the red giant stage.

Planetary habitability in the Solar System is the study that searches the possible existence of past or present extraterrestrial life in those celestial bodies. As exoplanets are too far away and can only be studied by indirect means, the celestial bodies in the Solar System allow for a much more detailed study: direct telescope observation, space probes, rovers and even human spaceflight.
Understanding planetary habitability is partly an extrapolation of the conditions on Earth, as this is the only planet known to support life.. Planetary habitability is the measure of a planet's or a natural satellite's potential to develop and maintain an environment hospitable to life. [1]
Venus is a hellhole. Despite being much closer to Earth than Mars, its climate is off-the-charts insane, with average temperatures of 864 degrees F, crushing barometric pressure, and did I mention ...
The new data suggests a form of chemical energy that can feed organic life has been discovered on one of Saturn's moons. NASA announces 'big step forward' in finding life beyond Earth: Saturn's ...
Today's Venus can be described as hellish: there is almost no water vapor, the carbon dioxide atmosphere is 90 times as thick as that on Earth and temperatures can reach a scorching 864 degrees.
The terraforming of Venus or the terraformation of Venus is the hypothetical process of engineering the global environment of the planet Venus in order to make it suitable for human habitation. [1] [2] [3] Adjustments to the existing environment of Venus to support human life would require at least three major changes to the planet's atmosphere ...
