Venus's 50-kilometer cloud layer offers Earth-like temperature and pressure, making floating cities scientifically feasible using acid-resistant materials and breathable-air buoyancy. Despite challenges from sulfuric acid and resource extraction, Venus provides better gravity and solar energy than Mars for long-term human habitation.
In 2020, astronomers detected phosphine—a gas produced by life on Earth—in Venus's toxic clouds, sparking debate about alien microbes versus unknown chemistry. After data controversies and a 2024 reconfirmation with ammonia detection, multiple missions (NASA's DAVINCI/VERITAS, ESA's EnVision, Rocket Lab's Morning Star) will investigate Venus's atmosphere by 2035. Whether phosphine signals life or reveals new planetary chemistry, the answer will redefine habitability, reshape our search for ex...
