Gas Indicates Possible Hints of Life in Venus's Clouds
In a study published on Monday, astronomers announced that they have detected the chemical signature for phosphine in Venus's clouds. Phosphine is a gas that is associated with life on Earth and its' presence indicates the possibility of life on Venus.
Despite the exciting news, several experts have already cautioned that, although Phosphine is considered a marker of life here on Earth, it is far from proof of life on another planet as there could be other causes we haven't considered.
According to study co-author Sara Seager, an MIT planetary scientist, her team “exhaustively went through every possibility and ruled all of them out: volcanoes, lightning strikes, small meteorites falling into the atmosphere. ... Not a single process we looked at could produce phosphine in high enough quantities to explain our team’s findings.”
Either way, more research is needed before scientists can draw a conclusion.
