However, none have been successful per say. “Phosphine as a Biosignature Gas in Exoplanet Atmospheres” by Clara Sousa-Silva, Sara Seager, Sukrit Ranjan, Janusz Jurand Petkowski, Zhuchang Zhan, Renyu Hu and William Bains, 22 November 2019, Astrobiology. If not, it will give a better understanding of the planet and the complex chemistry it possesses. Just because Venus was named after a woman and Mars was named after a man, doesn’t mean there’s anything going on. The detected presence of phosphine on Venus does convey the possibility of life there. According to a report by Reuters, the discovery of phosphine is a major breakthrough and could indicate life on the planet. Phosphine in the Atmosphere: Scientists Have Found Possible Signs of Alien Life on Venus Scientists have found anomalous amounts of Phosphine on Venus. This detection could point to extra-terrestrial “aerial” life in the Venusian atmosphere. The detection of phosphine could point to such extra-terrestrial “aerial” life. On the other hand, Venus is considered to be the most "hellish" planet in the solar system. Argument from ignorance fallacy. 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. 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. The abstract of the study published in the journal mentions clearly that the presence of phosphine on Venus is unexplained. Breaking Down the Science Behind Stunning Discovery, Aliens on Venus? Earth is the third. If it is clearly impossible on earth, it must be more so on venus. Phosphine is not a gas they usually look for when spotting signs of 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. Astronomers May Have Found a Signature of Life on Venus. This is why many speculate that the presence of phosphine on Venus could signal that there is actually life on the planet. Venus shares a lot in common with the Earth in terms of its size, proximity to the Sun, and possibly its past history.

That’s the truth. It also means that life itself must be very common, and there must be many other inhabited planets throughout our galaxy.” The abstract of the study published in the journal mentions clearly that the presence of phosphine on Venus is unexplained. It is considered as a marker for life. The discovery raises many questions, such as how any organisms could survive. “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 molecules float in the windblown clouds of Venus at altitudes of 55 to 80km, absorbing some of the millimeter waves that are produced at lower altitudes. That's less true for Jupiter and Saturn — scientists have been studying phosphine in those clouds for decades now. With the news of phosphine gas being detected in Venus's atmosphere many articles are stating that it is a sign of possible life. “The reason phosphine is special is, without life it is very difficult to make phosphine on rocky planets. Email address is optional. Again, argument from ignorance fallacy, plus an assertion without evidence (an assertion that is also clearly against every single piece of evidence there is; I refer you to the works of Charles Darwin, Lawrence Krause, and Richard Dawkins), topped with a healthy dose of hyperbole. 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.”. In short, the team of scientists, from the UK, US and Japan, have not found life form on Venus. 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. Venus is wrapped in a thick, toxic atmosphere that traps in heat. Even there, the atmosphere is teeming with sulphuric acid vapour which makes it extremely hostile, thereby reducing the chance of finding life forms. 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. If provided, your email will not be published or shared. ESO also plays a leading role in promoting and organising cooperation in astronomical research. Amazing to me that this could be a sign of life yet dividing cells in a human are not and abortion is ok because its not life. 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. Phosphine is very toxic to all forms of animal life, and even any exposure to man in very small amounts must be avoided. As molecules of phosphine float in the high clouds of Venus, they absorb some of the millimeter waves that are produced at lower altitudes. Credits: Image: ESO (European Southern Observatory)/M. An international team of astronomers recently announced the discovery of a rare molecule — phosphine — in the clouds of Venus. 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. Some ideas included sunlight, minerals blown upwards from the surface, volcanoes, or lightning, but none of these could make anywhere near enough of it. 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 JCMT is used to study our Solar System, interstellar and circumstellar dust and gas, evolved stars, and distant galaxies. Would it include depression? Phosphine also arises non-biologically in certain industrial settings. An international team of astronomers has detected phosphine on Venus, potentially signaling signs of life in the planet’s atmosphere, reports Shannon Stirone, Kenneth Chang and Dennis Overbye for The New York Times. 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 … (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. That said, any life in such a scorching hot and acidic atmosphere is unlikely to resemble much life we have on Earth. The team is composed of Jane S. Greaves (School of Physics & Astronomy, Cardiff University, UK [Cardiff]), Anita M. S. Richards (Jodrell Bank Centre for Astrophysics, The University of Manchester, UK), William Bains (Department of Earth, Atmospheric, and Planetary Sciences, Massachusetts Institute of Technology, USA [MIT]), Paul Rimmer (Department of Earth Sciences and Cavendish Astrophysics, University of Cambridge and MRC Laboratory of Molecular Biology, Cambridge, UK), Hideo Sagawa (Department of Astrophysics and Atmospheric Science, Kyoto Sangyo University, Japan), David L.

Like, it can support very different life than us. 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.Astronomers have speculated for decades that life could exist in Venus’s high clouds. Credit: ESO/M. 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. Traces of phosphine in Earth's atmosphere are directly linked to … However, Nature Astronomy strongly underlined that the discovery of phosphine on Venus is not enough evidence to confirm that there is life on Earth's twin planet. ), but claiming something is clearly impossible without even bothering to test it is foolish at best. “We have done our very best to explain this discovery without the need for a biological process. 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. On September 14, 2020, an international team of astronomers announced the discovery of a rare molecule — phosphine — in the clouds of Venus. “This is important because, if it is phosphine, and if it is life, it means that we are not alone. Get over it and move on. Scientists are trying to parse out whether a possible sign of life seen in Venus' clouds is truly there. In a study published in Nature Astronomy, the researchers have reported traces of phosphine in small concentration on Venus - of around 20 parts per billion, which is much more than what can be expected. Traces of phosphine in Earth's atmosphere are directly linked to … Microorganism Developed to Turn Discarded Cardboard Boxes Into Biodiesel, Detecting COVID-19 in Less Than 5 Minutes With a Paper-Based Electrochemical Sensor, Breaking the Power and Speed Limit of Lasers: New Fast, Powerful Compact Laser Invented, Solving a Paradox to Uncover Key Clues About Our Solar System’s History, New U.S. Research Confirms COVID-19 Complications: Lung, Kidney and Cardiovascular Issues, on "What Is Phosphine and Why Does It Point to Extra-Terrestrial Life Floating in the Clouds of Venus? You misunderstand, probably because coherent thought isn’t a strength for you. Earth bacteria are known to make phosphine: they take up phosphate from minerals or biological material, add hydrogen, and ultimately expel phosphine. DOI: 10.1089/ast.2020.2244 To produce phosphine, Earth bacteria take up phosphate from minerals or biological material and add hydrogen. Similar in structure but slightly smaller than Earth, it is the second planet from the sun. What makes an atmosphere? Plus, it takes a lot of energy to make phosphine, and life is a particularly energetic source. This is scientists clutching at straws, perhaps for funding. Phosphine gas, seen on Venus, is also produced by bacteria on Earth — but we don't know exactly how Phosphine is considered a marker of anaerobic life — … Signs of phosphine on Venus can’t be easily explained without life. Here's a chronology of missions to Venus, starting from 1961. It’s hitherto unknown to science, someone’s letting off gas giants. Absent of life, the production of phosphine requires great temperatures and pressures, and typically a source of hydrogen to react with. 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 live (sic) was by intelligent design there may be a possibility, but a living organism cannot come into existence without design and engineering”. “If it is clearly impossible on earth (sic), it must be more so on venus (sic)”. Credit: ESO/M. ESO carries out an ambitious programme focused on the design, construction and operation of powerful ground-based observing facilities enabling astronomers to make important scientific discoveries. They have yet to determine the unexplained chemical formation of … As NY Times reports, all these factors make it extremely difficult to visit Venus or even examine the supposed life form that exists on it. The detection of phosphine could point to such extra-terrestrial “aerial” life. ", Astronomers Find Possible Signs of Life on Venus, Why Scientists Believe There May Be Extra-Terrestrial Life Floating in the Atmosphere of Venus, Smelly and Poisonous Molecule May Be a Sure-Fire Sign of Extraterrestrial Life, Extra-Terrestrial “Aerial” Life on Venus? Phosphine, a toxic gas made up of one phosphorus and three hydrogen atoms (PH 3), commonly produced by organic life forms but otherwise difficult to make on rocky planets, was discovered in the middle layer of the atmosphere of Venus.This raises the tantalizing possibility that something is alive on our planetary neighbor. 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. On Monday, a team of scientists announced its members had detected phosphine gas in … The presence of phosphine in the atmosphere of Venus is something that was not expected and is "unexplained. Scientists studying the atmosphere of Venus say they've seen a chemical called phosphine, which on Earth is only produced by microbes and humans. SciTechDaily: Home of the best science and technology news since 1998. No, technically, they did not. It may not mean there's life on another world, but it's the closest we've come to confirmation. If it becomes life threatening, does that change your opinion? It also means that life itself must be very common, and there must be many other inhabited planets throughout our galaxy.”. Phosphine is widely accepted as being a "promising sign of life", when found in a rocky planet's atmosphere. Phosphine cannot be a product of a living organism for the following reasons. The researchers did not discover actual life forms, but noted that on Earth phosphine is produced by bacteria thriving in oxygen-starved environments. Seager noted that "the evidence is extremely strong that phosphine is associated with life in oxygen-free environments." This new image from ALMA, the Atacama Large Millimeter/submillimeter Array in which ESO is a partner, shows planet Venus. 1 No known creature can exist in concentrated Sulphuric acid situations. Great advice for religious zealots everywhere. 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.”, This artistic representation shows a real image of Venus, taken with ALMA, in which ESO is a partner, with two superimposed spectra taken with ALMA (in white) and the James Clerk Maxwell Telescope (JCMT; in grey). Scientists are excited they have found evidence that hints at signs of life in the clouds of Venus. 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. This time, they found, all signs pointed to phosphine, and a lot of it, ranging from 5 to 20 parts per billion. 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. Scientists have found possible signs of life in Venus's clouds. This could be indicative of the presence of alien life on a planet that has always been described as inhospitable. It has been detected in marshlands, rice … Gaseous signs of life on Venus aren't seen in follow-up observations Other researchers aren't finding phosphine, a sign of anaerobic life, in subsequent studies By Matthew Rozsa 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. Keep up with the latest scitech news via email or social media. ESO operates three unique world-class observing sites in Chile: La Silla, Paranal and Chajnantor. Weird how their god that turned loaves and fishes into a meal for thousands is such a terrible budgeter). But we mustn’t get irate. Surface temperatures reach a scorching 880 degrees Fahrenheit (471 degrees Celsius), hot enough to melt lead. Photograph: Greta Rybus Despite the aforementioned hostile conditions on Venus, human beings have tried to send up spacecrafts to explore the planet. 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. Phosphine is widely accepted as being a "promising sign of life", when found in a rocky planet's atmosphere. The detection is not proof of Venus life… For more on this discovery on SciTechDaily, see: More information One should not draw conclusions without evidence. Following their observations, they ran calculations to see whether these amounts could come from natural non-biological processes on the planet. ESO is also a major partner in two facilities on Chajnantor, APEX and ALMA, the largest astronomical project in existence. Now lets use that same logic on your position: if you contract an embryo due to your own action (sex without protection such as a condom) 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 the right to choose to remove it? DOI: 10.1089/ast.2018.1954, 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. Microbial life? 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? Astronomers May Have Found a Signature of Life on Venus Evidence indicates phosphine, a gas associated with living organisms, is present in the habitable region of Venus’ atmosphere. Instead, they found a substance, Phosphine, which is usually found on Earth either industrially or when microbes thrive in the absence of oxygen. Phosphine gas found in Venus’ atmosphere may be ‘a possible sign of life’ Astronomers detected signs of a smelly, toxic gas that microbes can make … Phosphine gas found in Venus’ atmosphere may be ‘a possible sign of life’ Astronomers detected signs of a smelly, toxic gas that microbes can make in the planet’s clouds “I should emphasize that life, as an explanation for our discovery, should be, as always, the last resort,” Sousa-Silva added. On Earth, phosphine is produced by certain types of bacteria. Phosphine produces a toxic effect on the organism's utilization of oxygen. The researchers examined potential non-biological sources such as volcanism, meteorites, lightning and various types of chemical reactions, but none appeared viable. In fact, some scientists reportedly believe that this could be more important than finding water traces on Mars. Here's what we know thus far about the stunning finding. The research continues to either confirm the presence of life or find an alternative explanation. (Have you ever noticed how churches always seem to need more and more money? 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 important because, if it is phosphine, and if it is life, it means that we are not alone. The search for life beyond Earth has largely revolved around our rocky red neighbor. It just means that some exotic process is producing phosphine, and our understanding of Venus needs work,” one of the researchers said. ; On rocky planets such as Venus and Earth, phosphine can only be made by life—whether human or microbe. Credit: ESO. The phosphine discovery presents the tantalizing possibility that life might be on Venus right now. It has been the year of pandemics, wildfires, asteroids zooming past Earth and now, aliens. On Earth, phosphine is produced by bacteria thriving in oxygen-starved environments. While previous robotic spacecraft have visited Venus, a new probe may be needed to confirm life. 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. Absent of life, the production of phosphine requires great temperatures and pressures, and typically a source of hydrogen to react with. Rather than a real feature on the planet, the patchiness of the disc may be due to the response of the interferometer to the very bright emission from Venus, which makes it hard to sample the largest scales accurately. Why it matters: The announcement that researchers may have spotted a signal of the gas phosphine in Venus' atmosphere was met with excitement by the public and scientists alike, heralded as a possible sign that microbes could live in the planet's clouds. Reuters adds that its surface and atmosphere are rich in oxygen compounds that would rapidly react with and destroy phosphine. Why are people so insistent that Venus can support life? Read our COVID-19 research and news. When observing the planet in the millimeter wavelength range, astronomers can pick up this phosphine absorption signature in their data, as … The new research may not be the first sighting of … Recently, Sousa-Silva and some of the researchers on this discovery presented phosphine as a possible biosignature because of … To top that hubris off by then extrapolating the argument from ignorance fallacy to another planet you know practically zilch about is simply breathtaking in its foolhardy arrogance. No images of alien life form have been captured, nor have the scientists been able to bring back specimens of microbes to examine them. I bet I can answer those questions on your behalf and be 100% accurate, as I’ve encountered you people before, but hey, prove me wrong. When observing the planet in the millimeter wavelength range, astronomers can pick up this phosphine absorption signature in their data, as a dip in the light from the planet. We can’t go to Venus. The detection of phosphine could point to such extra-terrestrial “aerial” life. It might just be how they communicate. By European Southern Observatory This summer, before the phosphine announcement, she and her co-authors published a speculative, hypothetical sketch of what life on Venus could look … 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. Potential Signs of Life Detected on the Inhospitable Planet, Also Read: '2020 Series Finale': Venus May Have Alien Life and Humans Already Want to Migrate. 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. Credit: ALMA (ESO/NAOJ/NRAO), Greaves et al. Watch our summary of the discovery. Astronomers have speculated for decades that life could exist in Venus’s high clouds. Phosphine is PH3 It stinks of fish or possibly garlic or maybe garlicky fish, it is toxic, flammable and explosive mixed with oxygen. 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.”. On Earth, microorganisms in “anaerobic” environments - ecosystems that do not rely on oxygen - produce phosphine. These non-biological sources were found to make at most one ten thousandth of the amount of phosphine that the telescopes saw. That’s why some astronomers believe the compound isn’t there. Writing in Nature Astronomy, the team stressed the presence of phosphine did not prove the presence of life on Venus. That said, any life in such a scorching hot and acidic atmosphere is unlikely to resemble much life we have on Earth. Scientists are trying to parse out whether a possible sign of life seen in Venus' clouds is truly there. This artistic illustration depicts the Venusian surface and atmosphere, as well as phosphine molecules. An argument posited without evidence must be dismissed without evidence. On Earth, the production of phosphine is associated with anaerobic life, which does not need oxygen to survive. There is phosphine in the atmospheres of Jupiter and Saturn, for example, but there it’s not a sign of life. But hey, you do you. But the team doesn’t think Venus can provide all three. Life that makes phosphine on Earth is found in swamps and sewage plants and the bottoms of lakes, she says, as well as in the intestines of animals — that's why phosphine … The Indian Express reports that this groundbreaking discovery was apparently made in 2017, but the scientists chose dig deeper and confirm before going public with it this year.
