Conceptual illustration of phosphine on Venus. In 2020, astronomers discovered that phosphine was present in the atmosphere of Venus. At present there is no known chemical mechanism that can create phosphine in this environment. Some astronomers believe that it can only have been created via biological processes, leading them to speculate about the possibility of microbial life in the atmosphere of this otherwise hellish planet. | |
