Today, the Royal Astronomical Society made a groundbreaking announcement. Scientists from a number of universities around the world using ground based telescopes determined the presence of phosphine (PH3) in Venus' upper atmosphere.
Phosphine takes an incredible amount of energy to produce. From our understanding, the only sources of phosphine on terrestrial worlds like Earth are from organisms. On Earth, phosphine is produced by anaerobic organisms like penguins. On gas giants like Jupiter and Saturn, they have the energy to produce phosphine, but Earth does not and from our understanding of Venus now, it shouldn’t have the energy to do so either.
The surface of Venus is an inhospitable hellhole, with temperatures of 425°C (800°F) or more and pressure 90x that at Earth's sea level. It's very unlikely for an organism to survive on its surface. Along with that, its atmosphere is toxic, containing sulfuric acid.
The presence of phosphine was found at about ~50km (32mi) at about 20°C (68°F), a very temperate climate on Venus. This region has been a concept for a “city” on Venus due to its hospitable environment. Despite that, its atmosphere is still toxic with sulfuric acid.
The clouds on Venus are not like Earth’s though, they are global encompassing and can last for thousands of years. In contrast, our own planet has cloud formations that last hours and are just a few kilometers in length. Despite that, in remote places on Earth, we have found the presence of organisms in cloud formations 35km (22mi) off the ground.
The presence of phosphine does not mean that life is there. There are a number of scenarios that it could be. It could be from chemical or geologic processes that are happening on the planet that we yet don't understand. This follows the trend of what we know about Venus: it's a ball of mystery under those clouds, there is much we yet don't know about it's clouds and what happens underneath them. In sum, what this means is that we found a gas that is typically a biosignature on terrestrial planets, and we yet can’t explain where it came from.
