The detection of phosphine on Venus demands confirmation on two levels. Chemistry labs across the globe are already investigating possible inorganic production routes, to see if anything besides life could account for the molecule’s presence in the atmosphere. The observation itself also requires independent verification. But there are considerable challenges to detecting phosphine’s other chemical fingerprints here on Earth.
The solution may come from space.
