The clouds of sulfuric acid that surround Venus are more inaccessible than astronomers imagine. Poor in the water and full of acid, life has no chance to survive there. But, the situation could be different from Jupiter’s side…
AllThere’s more to our solar system, scientists are discovering . Especially where they suspect that liquid water may be leaking. Or still flows… in handjob (Ireland) Today our attention is drawn to the fact that what really matters is not just the amount of water present, but the actual concentration The amount of water available for biological use.
This work was inspired by the discovery of September, announced last September.. Remember that phosphine is a molecule associated with the activity of what on Earth? anaerobic and that the discovery – ever since questioned – suggested that a microscopic form of life might exist on the hottest planet in our solar system.
But, based on laboratory experiments and observations returned by the investigation, researchers Queen’s University Emphasize: Water level inVenus is a hundred times less massive than the planet as we know it to be needed to support life. and also majority of The most tolerant of those who live on earth And acid, there would be no chance of survival on Venus.
Solar System Clouds as Habitable Environments? not so fast! It turns out that water activity is a major constraint, as it is almost always too low for the hardiest extremophiles to survive – especially on Venus… Holsworth et al.: https://t.co/ BzX78RwtIbpic.twitter.com/x3jXAWNOGB

Water activity as required data
The researchers worked on what they call water activity in clouds. A measure equivalent to humidity. Thus, liquid water would have an activity of 1 and a drought activity of 0. For survival, life would require a water activity of at least 0.585. Water activity in the clouds of Venus will not be high … 0.004! According to researchers, it is a hundred times more dry than. One of the driest regions of the world. Partly because the presence of acid reduces the activity of water.
In search of the Grail of life, here’s a hopeless new hope. yet thisThat certainly seems to be closing – at least for one life form that we know of on Earth, another may well be opening up. “We found that the state of the water – With an activity of just 0.585 – And the temperatures in Jupiter’s clouds may allow microbial-type life to survive”, John Holsworth, researcher, reveals .
However, the discovery does not suggest that life actually exists on Jupiter. “he needsAnd we can’t be sure that there are”, specifies the researcher. To verify this, further studies will need to look at Jupiter’s clouds. maybe three – the two and one from the European Space Agency ( ) – still going to learn more about Venus. for, perhaps, in his unequal circumstances Find a less unfavorable place for life.
