Life on Venus must be ‘A New Form of Life’ Now, Astronomers Claim

If life existed on Venus Scientists claim the new study is unlike any living thing. ever found on earth

In the late 2020s, questions about Venus’ habitability begin to come to light. Thanks to the detection of phosphine in the planet’s atmosphere. which some scientists suggest may be evidence of biosignature, hypothetically speaking.

While there are many researchers back and forth on this specific topic. This discovery sparked interest in the idea that Venus which is a famous poisonous and evil environment. Might be able to save a life

Coincidentally, NASA has launched two new missions to explore Venus – the first in decades – that might give us our best understanding of whether this inhospitable world will ever be habitable.

Those future discoveries are still years away. But new scientific research published this week suggests we may not be holding our breath for signs of life on Venus anytime soon.

According to an analysis led by microbiologist John Hallsworth of Queen̵

7;s University Belfast, the lack of water in Venus’ clouds prevents life from living there. or at least Life as we know it – like never before. enough water to make living things work

Researchers have found that Venus’ atmosphere is too arid for Earth-like creatures to survive. water activity measurement calculation which is a thermodynamic parameter that is equivalent to relative humidity to effectively determine the atmosphere.

“Water activity serves to determine the functional potential of microbial cells. So it’s an important factor in existence,” the researchers wrote in their study.

Water activity is measured on a scale from zero (lowest) to one (highest, similar to 100 percent humidity) as far as scientists know. Biological functions in living organisms are inactivated below the water activity level of 0.585 – with resistant xerophilic fungi. aspergillus Penicilioides represents the lowest known limit.

Unfortunately, Venus’ dry clouds which consists mainly of sulfuric acid aerosol not approaching 0.585 in terms of water activities with approximately ≤0.004, the researchers suggest.

in other words Venus’ atmosphere is 100 times more arid than this hypothetical age threshold, or as researchers have put it. “Two levels below the 0.585 limit for known extreme fanatics.”

in the same way Mars’ atmosphere may be considered too dry for life. Although the water activity level of ≤0.537 is slightly lower than the habitable period compared to Venus.

in terms of water activities Jupiter’s clouds show the level of biologically permissible water activity. But only between temperatures of –10 °C and 40 °C. But the researchers note that this is only the first step in assessing cloud habitability. The chemical composition in clouds can also affect clouds.

in the same way Water activity in Earth’s atmosphere is suitable for living things. but only in the lower troposphere where the upper stratosphere and the mesosphere are too dry to be habitable.

For other planets in the solar system, including Saturn, Uranus and Neptune, there is not enough information about the uniformity of their atmospheres to perform the same analysis. Although this may change in the future. Especially when the James Webb Space Telescope (JWST) is up and running.

Of course, just because the atmospheres of Venus and Mars are arid beyond the limits of the habitability of known extremists on Earth. This does not mean that life in these places is impossible.

Only that it must be very different from any living thing. known to science that’s all

“On the basis of the current study,” the researchers explained. “We have to envision a new species of life quality to invoke a convincing story about life in Venus’ atmosphere. At least for life as we know it.”

Research results were reported in natural astronomy.
