Venus's atmosphere consists mostly of carbon dioxide. Because nitrogen and oxygen are lighter than carbon dioxide, breathable-air-filled balloons will float at a height of about 50 km (31 mi). At this height, the temperature is a manageable 75 °C (348 K; 167 °F).
With extreme surface temperatures reaching nearly 735 K (462 °C; 863 °F) and an atmospheric pressure 92 times that of Earth, the conditions on Venus make water-based life as we know it unlikely on the surface of the planet.
Liquid-water environments have been found to exist in the absence of atmospheric pressure and at temperatures outside the HZ temperature range. For example, Saturn's moons Titan and Enceladus and Jupiter's moons Europa and Ganymede, all of which are outside the habitable zone, may hold large volumes of liquid water in subsurface oceans.

Venus is one of the most inhospitable planets, but OceanGate cofounder Guillermo Söhnlein wants to form a colony in its atmosphere. The Founder of OceanGate Wants to Send 1,000 People to Colonize ...
The current Venusian atmosphere has only ~200 mg/kg H 2 O(g) in its atmosphere and the pressure and temperature regime makes water unstable on its surface. Nevertheless, assuming that early Venus's H 2 O had a ratio between deuterium (heavy hydrogen, 2H) and hydrogen (1H) similar to Earth's Vienna Standard Mean Ocean Water of 1.6×10 −4, [7] the current D/H ratio in the Venusian atmosphere ...
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 ...

So maybe it’s best we leave Saturn exploration to uncrewed probes after all. In 2017, NASA’s Cassini probe sent us our closest view of Saturn to date. If you wanted to take a closer look at ...
