Confirming the presence of “life” at Venus needs a lot more work, primarily using telescopes, but the researchers say that ultimately it would be helpful to take in-situ measurements or “aerosol return”. The team believes their discovery is significant because they can rule out many alternative ways to make phosphine, but they acknowledge that confirming the presence of “life” needs a lot more work.

The European Southern Observatory’s Very Large Telescope (ESO’s VLT) has taken the first ever image of a young, Sun-like star accompanied by two giant exoplanets. lifeless) mechanisms on Venus?
Also at Paranal ESO will host and operate the Cherenkov Telescope Array South, the world’s largest and most sensitive gamma-ray observatory.
While the discovery of phosphine in Venus’s clouds came as a surprise, the researchers are confident in their detection. The discovery raises many questions, such as how any organisms could survive. To create the observed quantity of phosphine (which consists of hydrogen and phosphorus) on Venus, terrestrial organisms would only need to work at about 10% of their maximum productivity, according to the team.

The news—published today in Nature Astronomy—was made by scientists at Cardiff University and the University of Manchester in the UK, and the Massachusetts Institute of Technology (MIT) in the US.
Earlier this year a paper was published that posited that if NASA’s James Webb Space Telescope detected phosphine in the atmosphere of a rocky planet it would be an unmistakable sign of extraterrestrial life. The evidence for life on Venus is mixed. The international team, which includes researchers from the UK, US and Japan, estimates that phosphine exists in Venus’s clouds at a small concentration, only about twenty molecules in every billion. Images of systems with multiple exoplanets are extremely rare, and — until now — astronomers had never directly observed more than one planet orbiting a star similar to the Sun.

These non-biological sources were found to make at most one ten thousandth of the amount of phosphine that the telescopes saw. More observations of Venus and of rocky planets outside our Solar System, including with ESO’s forthcoming Extremely Large Telescope, may help gather clues on how phosphine can originate on them and contribute to the search for signs of life beyond Earth.

There’s so much of it in the clouds of Venus that it’s more likely from another source.
Some bacteria on Earth make phosphine, taking up phosphate from minerals or biological material, adding hydrogen, and expelling phosphine. Additional funding support is provided by the STFC and participating universities in the UK and Canada. So although phosphine can be produced by abiotic mechanisms, there’s so much of it in the clouds of Venus that it’s more likely to come from another source.

In this lower cloud layer there are favorable-ish conditions for microbial life, including moderate temperatures and pressures. The team is composed of Jane S.

A belt of clouds about 50 km above Venus have long been thought of as a place just as likely as anywhere else in the Solar System to host life. In the search for exoplanets that could host life, astronomers look for “biosignature gases”—and phosphine is one of them.
ESO/M. Cardiff, UK On Earth, some microbes can cope with up to about 5% of acid in their environment — but the clouds of Venus are almost entirely made of acid.”.
There could be microbial life in the clouds of Venus.
A team led by Greaves searched for molecules in the atmosphere of Venus that shouldn’t be there and unexpectedly found a signal of phosphine.
A new analysis hints that there may not be much phosphine on Venus after all. Email: d.clements@imperial.ac.uk, Paul Rimmer (study author)
Despite the cautious nature of the news, it’s a big story for anyone interested in the hunt for life beyond Earth. Each set item is bound on equip.
“Processing the data was tricky, though, as ALMA isn’t usually looking for very subtle effects in very bright objects like Venus. Only one ten thousandth, in fact.
“When we got the first hints of phosphine in Venus’s spectrum, it was a shock!”. Confirming their discovery required using 45 antennas of the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, a more sensitive telescope in which the European Southern Observatory (ESO) is a partner.
