According to Dr David L Clements, Reader in Astrophysics at Imperial College London, the discovery is going to shift the world’s attention towards Venus.
He told Express.co.uk: “It’s going to change a number of priorities. Mars has been our favourite planetary destination for a long time, and, in the search for life, after that comes Enceladus and Europa in our own solar system.
“Our result changes that, and means that there will be much more of a focus on Venus to work out what is going on there.
“After that, it rather depends on what is producing the phosphine. If it is life, then there is going to be a lot happening.
“If not, we’ll better understand Venus and what would have to be some very odd and complicated chemistry.”
