While interested in all aspects of space exploration, his primary passion is planetary science. Come travel with us! Image via Seager et al.

They would cycle through different layers of the atmosphere, never reaching the ground, and survive the most extreme conditions by transitioning into a temporary dormant state. Two telescopes in Hawaii and Chile spotted in the thick Venutian clouds the chemical signature of phosphine, a noxious gas that on Earth is only associated with life, according to a study in Monday’s journal Nature Astronomy. They have detected phosphine, a rare molecule that is a sign of microbial life. (The icy moons of Jupiter and Saturn are also possible places.) That’s a pretty definitive statement to make. The surface of Venus is a hellish landscape that no carbon-based lifeforms are likely to be able to survive – temperatures can reach almost 900 F/500 C – but there is a ‘habitable zone’ 48-60 kilometres up in the planet’s cloudy atmosphere that is similar to Earthly conditions, at least in terms of temperature and pressure. Phosphine, a stinky, toxic and flammable gas found on Earth, has been detected in the atmosphere of Venus. A proposed life cycle for microbes in Venus’ atmosphere. Other scientists, including David Grinspoon, have written about the possibility of life in Venus’ clouds before as well. The temperate zone in Venus’ atmosphere where temperatures and pressures are more habitable for life. The research team will continue its search for the origin of the phosphine gas detected on Venus, as well as look for other unexpected gases in its atmosphere. Shockingly, it might not be. Possible signs of life have been detected on Venus. Researchers have spotted phosphine, a rare and toxic gas, in the atmosphere of our neighbouring planet, suggesting that …
(5) The droplets grow large enough that they sink through the atmosphere, where they begin to evaporate due to higher temperatures, prompting microbes to transform into spores that float in the lower haze layer. However, any microbes on Venus will likely be very different from the ones on Earth to survive in hyper-acidic conditions. While the discovery is surprising, scientists have speculated for years that microbial life might exist in Venus’ atmosphere. These microbes would live high above the scorching temperatures of Venus’s surface, but would have the ability to live in a very acidic environment. From Souva-Silva’s 2019 article in Scientific American about phosphine: Life as we know it is likely only one island in the vast archipelago of possibilities for biology. Mars has been considered the best possibility for life to be possible after Earth to host microbial activity in the past or even in the future. So scientists turned their attention elsewhere, but no definitive signs of life have been found anywhere else. The researchers made the detection using the James Clerk Maxwell Telescope in Hawaii and the ALMA telescope in Chile.
It’s one of the last places you’d expect to find any kind of life.
An international team of astronomers has found tentative but highly compelling evidence. Last month, another study discussed in Astronomy magazine and elsewhere, showed how microbes could theoretically exist in Venus’ atmosphere by finding refuge inside drops of sulphuric acid that also contain some water.

On the other hand, the residents of these planets would probably find us disgusting too (a problem for interplanetary diplomacy to overcome). Share Signs of Life Found On Venus on Twitter . Unofficially, at this point ahead of the lifting of the embargo: after six months of processing the data from the observations, those results appear to be that they are convinced phosphine is present in Venus’s clouds. Venus is also closer to the Sun, which provides the necessary warmth for life as we know it.
