Where it’s found on Earth—in swamps, penguin dung heaps and the bowels of some badgers and fish—it’s said to smell like rotting fish or garlic. Subscribe to the ESO Media Newsletter in your language. That may not sound like much, but it’s actually more than could be expected to occur form non-biological sources. And on Cerro Armazones, close to Paranal, ESO is building the 39-metre Extremely Large Telescope, the ELT, which will become “the world’s biggest eye on the sky”. Confirming the existence of life on Venus's atmosphere would be a major breakthrough for astrobiology; thus, it is essential to follow-up on this exciting result with theoretical and observational studies to exclude the possibility that phosphine on rocky planets may also have a chemical origin different than on Earth.”. ESO-Sets, ESO-Skillbook and ESO-Housing are becoming ESO-Hub. “I thought we’d just be able to rule out extreme scenarios, like the clouds being stuffed full of organisms,” said team leader Jane Greaves of Cardiff University in the UK, who first spotted signs of phosphine in observations from the James Clerk Maxwell Telescope (JCMT), operated by the East Asian Observatory, in Hawaiʻi. Manchester, UK a ZeniMax Media company. 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.

Although the high clouds of Venus have temperatures up to a pleasant 30 degrees Celsius, they are incredibly acidic — around 90% sulphuric acid — posing major issues for any microbes trying to survive there. Tel: +49 89 3200 6670 The evidence for life on Venus is mixed. Earth bacteria are known to make phosphine: they take up phosphate from minerals or biological material, add hydrogen, and ultimately expel phosphine. UK ALMA Regional Centre and University of Manchester This research was presented in the paper “Phosphine Gas in the Cloud Decks of Venus” to appear in Nature Astronomy. Some ideas included sunlight, minerals blown upwards from the surface, volcanoes, or lightning, but none of these could make anywhere near enough of it. If the theory holds about where phosphine must originate from, then we’re talking anaerobic, acid-resistant bacteria. London, UK Kornmesser/L.

This artistic impression depicts our Solar System neighbour Venus, where scientists have confirmed ... [+] the detection of phosphine molecules, a representation of which is shown in the inset. You may opt-out by. Since these molecules float in the high clouds of Venus (though not around the polar caps), they absorb some of the millimeter waves that are produced at lower altitudes. It’s hot enough down there to melt metal and its surface often gets coated in sulfuric acid rain. The discovery raises many questions, such as how any organisms could survive.

Massachusetts Institute of Technology Cambridge, USA “When we got the first hints of phosphine in Venus’s spectrum, it was a shock!”, says team leader Jane Greaves of Cardiff University in the UK, who first spotted signs of phosphine in observations from the James Clerk Maxwell Telescope (JCMT), operated by the East Asian Observatory, in Hawaiʻi. Bind on Equip. ESO Public Information Officer “The non-biological production of phosphine on Venus is excluded by our current understanding of phosphine chemistry in rocky planets' atmospheres,” said Leonardo Testi, European Southern Observatory (ESO) astronomer and ALMA European Operations Manager, who did not participate in the new study. The researchers say organisms on Venus would only need to work at about 10% of their maximum productivity to produce the levels of phosphine the telescopes detected.

Any organisms on Venus will probably be very different to their Earth cousins, but they too could be the source of phosphine in the atmosphere. ESO is also a major partner in two facilities on Chajnantor, APEX and ALMA, the largest astronomical project in existence. The European Southern Observatory (ESO) is the foremost intergovernmental astronomy organisation in Europe and the world’s most productive ground-based astronomical observatory by far. That means organisms at Venus—though likely to be very different to anything found on Earth cousins—could be the source of phosphine in its atmosphere. However, despite the high clouds of Venus having temperatures up to a pleasant 86 ºF/30ºC degrees Celsius, they about 90% sulphuric acid, which would make it difficult for microbes trying to survive there. Could the traces of phosphine come from non-biological abiotic (i.e. Are you a journalist? “To our great relief, the conditions were good at ALMA for follow-up observations while Venus was at a suitable angle to Earth. These molecules float in the windblown clouds of Venus at altitudes of 35 to 50 miles/55 to 80km. Kornmesser & NASA/JPL/Caltech. After seeing signs of it in observations from the JCMT at a wavelength of about 1 millimetre, the scientists confirmed their discovery required using 45 antennas of the Atacama Large Millimeter/submillimeter Array (ALMA) —currently the largest radio telescope in the world. The Joint ALMA Observatory (JAO) provides the unified leadership and management of the construction, commissioning and operation of ALMA. Cardiff, UK 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”. 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. Cambridge, USA Each set item is bound on equip. However, the MIT researchers found that phosphine is produced by anaerobic organisms, such as bacteria and microbes, which don’t require oxygen. Email: d.clements@imperial.ac.uk, Paul Rimmer (study author) It utilizes the old Fighters and Mages Guilds' halls located in this ancient Nirn city. Following their observations, they ran calculations to see whether these amounts could come from natural non-biological processes on the planet. In fact, the paper reads: “There are substantial conceptual problems for the idea of life in Venus’ clouds—the environment is extremely dehydrating as well as hyper-acidic.”.

So the researchers did the math on how much phosphine could be produced by: However, their calculations indicate that these non-biological sources couldn’t make enough phosphine to account for what the telescopes detected. ESO/M. 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. “The discovery raises many questions, such as how any organisms could survive,” said team member Clara Sousa Silva of the Massachusetts Institute of Technology in the US. You can also find it on Guild Traders. “Confirming the existence of life on Venus's atmosphere would be a major breakthrough for astrobiology ... it is essential to follow-up on this exciting result with theoretical and observational studies to exclude the possibility that phosphine on rocky planets may also have a chemical origin different than on Earth.”. Also at Paranal ESO will host and operate the Cherenkov Telescope Array South, the world’s largest and most sensitive gamma-ray observatory. 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. “Processing the data was tricky, though, as ALMA isn’t usually looking for very subtle effects in very bright objects like Venus. The Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. “To our great relief, the conditions were good at ALMA for follow-up observations while Venus was at a suitable angle to Earth,” said team member Anita Richards of the UK ALMA Regional Centre and the University of Manchester. Created by Alcast So phosphine comes from organisms—albeit extremophiles—which makes phosphine a pure biosignature. the detection of phosphine molecules, a representation of which is shown in the inset. Garching bei München, Germany All Rights Reserved, This is a BETA experience.

The researchers emphasize that the detection of phosphine is not robust evidence for life, only for anomalous and unexplained chemistry. So by observing Venus in the millimeter wavelength astronomers could see the tell-tale signs of phosphine absorption in their data—essentially as a dip in the light from Venus.

Astronomers have speculated for decades that high clouds on Venus could offer a home for microbes — floating free of the scorching surface but needing to tolerate very high acidity. Both facilities observed Venus at a wavelength of about 1 millimetre, much longer than the human eye can see — only telescopes at high altitude can detect it effectively.  “In the end, we found that both observatories had seen the same thing — faint absorption at the right wavelength to be phosphine gas, where the molecules are backlit by the warmer clouds below,” said Greaves. Email: cssilva@mit.edu, Leonardo Testi (contact for independent comment on the study) The detection of phosphine could point to such extra-terrestrial “aerial” life. Cambridge, UK ESO/M. Additional funding support is provided by the STFC and participating universities in the UK and Canada. Opinions expressed by Forbes Contributors are their own. 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. However, the pure form of phosphine is odorless. While the discovery of phosphine in Venus’s clouds came as a surprise, the researchers are confident in their detection. “In the end, we found that both observatories had seen the same thing — faint absorption at the right wavelength to be phosphine gas, where the molecules are backlit by the warmer clouds below,” adds Greaves, who led the study published today in Nature Astronomy. These non-biological sources were found to make at most one ten thousandth of the amount of phosphine that the telescopes saw. The other explanation is that there is some weird chemistry going on in the cloud tops of Venus that we just don’t understand. Processing the data was tricky, though, as ALMA isn’t usually looking for very subtle effects in very bright objects like Venus,” says team member Anita Richards of the UK ALMA Regional Centre and the University of Manchester.

ESO also plays a leading role in promoting and organising cooperation in astronomical research. Traces of phosphine (PH3)—a gas thought to be a sign of life—has been inferred in the atmosphere of Venus by scientists performing an experiment out of pure curiosity. Phosphine, consisting of hydrogen and phosphorus, is a colorless, smelly, flammable, toxic gas on Earth. If life arose on two planets in the Solar System then it may be commonplace in the Universe.

Another related study by some of the same authors, "Phosphine as a Biosignature Gas in Exoplanet Atmospheres", was published in Astrobiology in January 2020. 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. 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. 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. Wisdom of Vanus is a Set in Elder Scrolls Online (ESO). ZeniMax, Despite the cautious nature of the news, it’s a big story for anyone interested in the hunt for life beyond Earth. 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.”. An international team of astronomers today announced the discovery of a rare molecule — phosphine — in the clouds of Venus. There could be microbial life in the clouds of Venus.

Another team member, Clara Sousa Silva of the Massachusetts Institute of Technology in the US, has investigated phosphine as a “biosignature” gas of non-oxygen-using life on planets around other stars, because normal chemistry makes so little of it. 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. There’s so much of it in the clouds of Venus that it’s more likely from another source. ESO operates three unique world-class observing sites in Chile: La Silla, Paranal and Chajnantor. A new analysis hints that there may not be much phosphine on Venus after all. It has 16 Member States: Austria, Belgium, the Czech Republic, Denmark, France, Finland, Germany, Ireland, Italy, the Netherlands, Poland, Portugal, Spain, Sweden, Switzerland and the United Kingdom, along with the host state of Chile and with Australia as a Strategic Partner.
