UK Mission to Search for Life in Venus's Clouds
A UK-led mission aims to definitively answer whether life exists on Venus. The mission will send a probe to search for microbial life, not on the surface, but within Venus's clouds. Recent discoveries of phosphine and ammonia—potential biosignatures—in the Venusian clouds have fueled this investigation. While these gases are produced by biological activity and industrial processes on Earth, their origin on Venus remains a mystery. Given Venus's harsh surface conditions, microbial life in the cooler, higher altitudes of the clouds is a more plausible explanation. The mission, VERVE, will hitch a ride on the ESA's EnVision mission, launching in 2031, and conduct an independent atmospheric survey upon arrival. Previous detections of phosphine were controversial, but further research suggests its presence varies and is destroyed by sunlight, explaining discrepancies in earlier findings. The detection of ammonia further strengthens the case for investigating this possibility.
