This summer, before the phosphine announcement, she and her co-authors published a speculative, hypothetical sketch of what life on Venus could look … Potential Signs of Life Detected on the Inhospitable Planet, '2020 Series Finale': Venus May Have Alien Life and Humans Already Want to Migrate, Kareena Kapoor Khan Shares Sharmila Tagore's Throwback Pic on Her Birthday, Desis are Imagining Mysterious Monolith Popping up in India and the Results are On-point, Xiaomi Mi Notebook 14 e-Learning Edition Review: Valiantly Proves Core i3 Laptops Need Not Be Irritating, Ravi Dubey and Sargun Mehta Celebrate 7th Wedding Anniversary with Romantic Pictures, WWE: Becky Lynch, Seth Rollins Announce Birth of First Child in Instagram Photo, Bharat Band Protest: Farmers Launch Nationwide Strike Over New Laws, Hina Khan Shares Alluring Pictures From Her Maldives Vacation. It can only be produced by organisms in oxygen-free environments or artificially in labs. Credit: ESO/M. Credit: ESO. Phosphine gas found on Venus that could indicate signs of life Astronomers have found a key gas on Venus linked to human life, raising the “enticing possibility” the planet could be supporting life in some form. On Earth, the production of phosphine is associated with anaerobic life, which does not need oxygen to survive. Gas spotted in Venus’s clouds could be a sign of alien life. By … The Joint ALMA Observatory (JAO) provides the unified leadership and management of the construction, commissioning and operation of ALMA. Phosphine is a compound made from phosphorus and hydrogen, and on Earth its only natural source is tiny microbes that live in oxygen-free environments. 2 If live was by intelligent design there may be a possibility, but a living organism cannot come into existence with out design and engineering. 1 No known creature can exist in concentrated Sulphuric acid situations. Phosphine is not a gas they usually look for when spotting signs of life. After detailed and thorough study, the scientists have not been able to determine the source of the gas. I’ll attempt to clarify: the pro choice spectrum does not claim an embryo is not alive, we state it is not capable of surviving on its own. According to a report by Reuters, the discovery of phosphine is a major breakthrough and could indicate life on the planet. Venus is Earth’s closest planetary neighbour. It just means that some exotic process is producing phosphine, and our understanding of Venus needs work,” one of the researchers said. Why are people so insistent that Venus can support life? The presence of phosphine raises the remarkable possibility that there is something unusual going on in the planet’s atmosphere. Something’s farting at the human race. When observing the planet in the millimeter wavelength range, astronomers can pick up this phosphine absorption signature in their data, as … It is too early to say whether phosphine is also a sign of life on Venus – but no other explanation so far proposed seems to fit. The administrator of NASA, Jim Bridenstine, also said on Twitter that it is time to prioritise Venus, which has long been ignored owing to its hostile environment. To produce phosphine, Earth bacteria take up phosphate from minerals or biological material and add hydrogen. Photograph: Greta Rybus For long, scientists have focused on Mars and traces of water on it as the most likely planet to have a life form on it. The detection is not proof of Venus life… (NASA/File Photo) Scientists said on Monday they have detected in the harshly acidic clouds of Venus a gas called phosphine that indicates microbes may inhabit Earth’s inhospitable neighbour, a tantalizing sign of potential life beyond Earth. This new image from ALMA, the Atacama Large Millimeter/submillimeter Array in which ESO is a partner, shows planet Venus. 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. Here's what we know thus far about the stunning finding. Keep up with the latest scitech news via email or social media. Currently, the Japanese spacecraft Akatsuki is the only one monitoring the planet. Phosphine is PH3 It stinks of fish or possibly garlic or maybe garlicky fish, it is toxic, flammable and explosive mixed with oxygen. That said, any life in such a scorching hot and acidic atmosphere is unlikely to resemble much life we have on Earth. Clara Sousa-Silva focused on phosphine because relatively little was known about the compound. The molecules were detected in the Venusian high clouds in data from the James Clerk Maxwell Telescope and the Atacama Large Millimeter/submillimeter Array, in which ESO is a partner. The planet has massive concentrations of carbon dioxide and the thick atmosphere of the planet exerts a pressure of 1,300 pounds per square inch on whatever is present on the surface. Earth bacteria are known to make phosphine: they take up phosphate from minerals or biological material, add hydrogen, and ultimately expel phosphine. An argument posited without evidence must be dismissed without evidence. It may not mean there's life on another world, but it's the closest we've come to confirmation. The presence of phosphine in the atmosphere of Venus is something that was not expected and is "unexplained. Once reports of alien life on Venus began doing the rounds on social media, several pointed out that it was now time to prioritise Venus over other planets like Mars. Both facilities observed Venus at a wavelength of about 1 millimeter, much longer than the human eye can see — only telescopes at high altitude can detect it effectively. 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. If provided, your email will not be published or shared. Instead, they found a substance, Phosphine, which is usually found on Earth either industrially or when microbes thrive in the absence of oxygen. On September 14, 2020, an international team of astronomers announced the discovery of a rare molecule — phosphine — in the clouds of Venus. ESO also plays a leading role in promoting and organising cooperation in astronomical research. But hey, you do you. It’s hitherto unknown to science, someone’s letting off gas giants. They were detected in Venus’s high clouds in data from the James Clerk Maxwell Telescope and the Atacama Large Millimeter/submillimeter Array, in which ESO is a partner. One should not draw conclusions without evidence. In fact, some scientists reportedly believe that this could be more important than finding water traces on Mars. Calçada. With the news of phosphine gas being detected in Venus's atmosphere many articles are stating that it is a sign of possible life. 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. Weird how their god that turned loaves and fishes into a meal for thousands is such a terrible budgeter). Another related study by some of the same authors, “Phosphine as a Biosignature Gas in Exoplanet Atmospheres,” was published in Astrobiology in January 2020. This is the holy grain of evolution and all the evidence points to the fact that it is not only impossible, it is ridiculously impossible. The observed quantity of Phosphine on Venus could not be produced by any natural processes, hinting at the existence of alien life … The Atacama Large Millimeter/submillimeter Array (ALMA), an international astronomy facility, is a partnership of ESO, the U.S. National Science Foundation (NSF), and the National Institutes of Natural Sciences (NINS) of Japan in cooperation with the Republic of Chile. Earth is the third. This research was presented in the paper “Phosphine Gas in the Cloud Decks of Venus” published 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. The researchers did not discover actual life forms, but noted that on Earth phosphine is produced by bacteria thriving in oxygen-starved environments. A parallel would be tapeworms: if you contract tapeworms through your own action (eating without protection such as proper cooking), are you obligated to allow that parasite to fulfill that portion of its life cycle inside of you (at your expense) or do you have the right to security of your person against unwanted intrusion and therefore to choose to remove it? Reuters adds that its surface and atmosphere are rich in oxygen compounds that would rapidly react with and destroy phosphine. That's less true for Jupiter and Saturn — scientists have been studying phosphine in those clouds for decades now. Absent of life, the production of phosphine requires great temperatures and pressures, and typically a source of hydrogen to react with. Scientists are trying to parse out whether a possible sign of life seen in Venus' clouds is truly there.

It’s too early to say whether phosphine is also a sign of life on Venus – but no other explanation so far proposed seems to fit. No images of alien life form have been captured, nor have the scientists been able to bring back specimens of microbes to examine them. Venus shares a lot in common with the Earth in terms of its size, proximity to the Sun, and possibly its past history. It also means that life itself must be very common, and there must be many other inhabited planets throughout our galaxy.”. The presence of phosphine in the atmosphere of Venus is something that was not expected and is "unexplained. "The presence of PH3 is unexplained after exhaustive study of steady-state chemistry and photochemical pathways, with no currently known abiotic production routes in Venus’s atmosphere, clouds, surface and subsurface, or from lightning, volcanic or meteoritic delivery," says the first part of the study. Phosphine in the Atmosphere: Scientists Have Found Possible Signs of Alien Life on Venus Scientists have found anomalous amounts of Phosphine on Venus. DOI: 10.1038/s41550-020-1174-4, “The Venusian Lower Atmosphere Haze as a Depot for Desiccated Microbial Life: A Proposed Life Cycle for Persistence of the Venusian Aerial Biosphere” by Sara Seager, Janusz J. Petkowski, Peter Gao, William Bains, Noelle C. Bryan, Sukrit Ranjan and Jane Greaves, 13 August 2020, Astrobiology. That’s why some astronomers believe the compound isn’t there. I have been reading abut how it is produced by bacteria and such but on Wikipedia I have also found out that such gas is present in Jupiter's atmosphere. If not, it will give a better understanding of the planet and the complex chemistry it possesses. Breaking Down the Science Behind Stunning Discovery, Aliens on Venus? ), but claiming something is clearly impossible without even bothering to test it is foolish at best. Astronomers have speculated for decades that life could exist in Venus’s high clouds. Kornmesser & NASA/JPL/Caltech . She comments: “Finding phosphine on Venus was an unexpected bonus! “This is important because, if it is phosphine, and if it is life, it means that we are not alone. As molecules of phosphine float in the high clouds of Venus, they absorb some of the millimeter waves that are produced at lower altitudes. “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. “Something must be creating the phosphine on Venus as fast as it is being destroyed,” said study co-author Anita Richards, an astrophysicist associated with the University of Manchester in England. While the discovery of phosphine in Venus’s clouds came as a surprise, the researchers are confident in their detection. Calçada & NASA/JPL/Caltech, ESO astronomer and ALMA European Operations Manager Leonardo Testi, who did not participate in the new study, says: “The non-biological production of phosphine on Venus is excluded by our current understanding of phosphine chemistry in rocky planets’ atmospheres. The JCMT is used to study our Solar System, interstellar and circumstellar dust and gas, evolved stars, and distant galaxies. “I should emphasize that life, as an explanation for our discovery, should be, as always, the last resort,” Sousa-Silva added. Here's a chronology of missions to Venus, starting from 1961. A sign of life? “Get over it and move on”. Very important difference. These include sewage plants, swamps, rice fields, marshlands, lake sediments and the excrements and intestinal tracts of many animals. Phosphine is not a gas they usually look for when spotting signs of life. Phosphine cannot be a product of a living organism for the following reasons. Only later did it emerge as a promising sign of life. The scientists who made big waves in September for their study about the presence of possible markers of life on Venus have adjusted their findings, revealing much fainter traces of phosphine … The discovery of phosphine gas in the clouds of Venus could possibly indicate signs of life on the planet, scientists have said. The search for life in our solar system got a lot more exciting this week. Kornmesser/L. This artistic illustration depicts the Venusian surface and atmosphere, as well as phosphine molecules. This discovery was unexpected and a potential game changer. “If live (sic) was by intelligent design there may be a possibility, but a living organism cannot come into existence without design and engineering”. Life on Venus announcement: The discovery of phosphine in the atmosphere of Venus has triggered excitement as a possible sign of life on that planet. 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. An accompanying paper by some of team members, titled “The Venusian Lower Atmosphere Haze as a Depot for Desiccated Microbial Life: A Proposed Life Cycle for Persistence of the Venusian Aerial Biosphere,” was published in Astrobiology in August 2020. Brings to mind a proverb about beginning with certainty.. “No known creature can exist in concentrated Sulphuric (sic) acid situations”. We can’t go to Venus. "This is an astonishing and ‘out of the blue’ finding,” says Prof. Sara Seager. Phosphine also arises non-biologically in certain industrial settings. This is, by far, the most credible evidence of the presence of life outside our planet. Evidence indicates phosphine, a gas associated with living organisms, is present in the habitable region of Venus ’ atmosphere. Phosphine is a phosphorus atom with three hydrogen atoms attached (PH 3) – is highly toxic to people. The molecular makeup of a planet’s atmosphere normally depends on what its parent star is made of, the planet’s position in its star’s system, and the chemical and geological processes that take place given these conditions. On Earth, phosphine is produced by bacteria thriving in oxygen-starved environments. SciTechDaily: Home of the best science and technology news since 1998. On Earth, phosphine is considered a conclusive sign of life. It has been the year of pandemics, wildfires, asteroids zooming past Earth and now, aliens. The JCMT is operated by the East Asian Observatory on behalf of NAOJ; ASIAA; KASI; CAMS as well as the National Key R&D Program of China. The gas has been detected in the highly toxic atmosphere of Venus, as reported by New York Times. ; On rocky planets such as Venus and Earth, phosphine can only be made by life—whether human or microbe. The new research may not be the first sighting of … And on Cerro Armazones, close to Paranal, ESO is building the 39-meter Extremely Large Telescope, the ELT, which will become “the world’s biggest eye on the sky.”. Read our COVID-19 research and news. 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.
