In 2010, scientists waiting to use the William Herschel Telescope in the Canary Islands captured a brief 36 minutes of images of Venus. What they discovered, hidden in the data, was a series of planetwide concentric rings in the upper atmosphere.
Reexamining old data showed that the atmosphere on Venus is approximately 62% water trapped in hydrated compounds.
BepiColombo made two flybys of Venus on its journey to Mercury. The spacecraft found carbon and oxygen escaping into space in a previously unexplored region of Venus’ magnetosphere.
