Exploration of Venus

The video explores Francesco Bianchini's early telescopic observations of Venus, where he mistakenly identified dark regions as bodies of water. Despite his errors, his work marked a significant step in astronomy. The video also discusses historical theories and science fiction about Venus, imagining it as a swampy jungle world. The Soviet Venera 9 mission in 1975 provided the first images of Venus's surface, revealing a harsh environment with extreme temperatures and sulfuric acid clouds. These findings debunked earlier misconceptions and highlighted Venus's inhospitable conditions.
