In addition to criticism, supporting evidence was also inspired by the team's original paper—which was also presented at VEXAG on November 17. Although that concentration is low, the researchers point out that phosphine produced by life on Earth can be found at even lower concentrations in … Venus lacks the high temperatures and pressures to form phosphine the way gas giants such as Jupiter do; thus another explanation for its presence is required. Science News was founded in 1921 as an independent, nonprofit source of accurate information on the latest news of science, medicine and technology. A gas that could indicate signs of life has been found on Venus. In fact, phosphine has been detected in Jupiter's atmosphere, where it forms as a result of planet-sized convective storms that generate tremendous amounts of energy. Some other molecules also absorb light near that wavelength, but those either couldn’t explain the whole signal or seemed improbable, Greaves says. Signs of phosphine first showed up in data taken with the James Clerk Maxwell Telescope in Hawaii. Traces of a pungent gas that waft through the clouds of Venus may be emanations from aerial organisms – microbial life, but not as we know it.. Astronomers detected phosphine 30 miles up in … Deep within Jupiter and Saturn, high temperatures and extreme pressures combine to create phosphine spontaneously. [17] Phosphine gas was first detected on Venus in 2017 by Jane Greaves, an astrobiologist and professor of astronomy at the University of Cardiff in Wales and the lead author of the new study. In any case, these results demand further investigation and have led to renewed proposals for missions to Venus," possibly in the form of a balloon or an airship. They found that phosphine on Venus is a minor gas, existing at a concentration of about 20 out of every billion molecules in the atmosphere. She hopes other scientists will come up with other explanations. He is the author of The Genealogical Adam and Eve and the founding scientist of the blog Peaceful Science. References and notes. While scientists have traditionally not suspected that life exists on Venus, astronomers have discovered signs of a chemical called phosphine in … Lisa Grossman is the astronomy writer. “I think a floating plastic factory is a less plausible explanation than just saying there’s phosphine.”. Venus' phosphine puzzle. They have yet to determine the unexplained chemical formation of the gas. When she was analyzing the observations, “I thought ‘Oh, I must have done it wrong.’”, So the team checked again with a more powerful telescope, the Atacama Large Millimeter/submillimeter Array in Chile, in March 2019. Measurements of trace-gases in planetary atmospheres help us explore chemical conditions different to those on Earth. In the meantime, Greaves and other researchers hope to have more time with Earth-based telescopes (including ALMA) to confirm the presence of phosphine. Published online September 14, 2020. doi:10.1038/s41550-020-1174-4. And it obligates us to go investigate further.”. Press Release - Source: astro-ph.EP; Posted September 14, 2020 10:45 PM; Comments; Spectra of Venus obtained with ALMA. Venus' phosphine puzzle Axios - Wed 25 Nov 11:15 GMT. It is phosphine that indicates the presence of life on earth. Scientists are trying to parse out whether a possible sign of life seen in Venus' clouds is truly there. The aim was a benchmark for future developments, but unexpectedly, our initial observations suggested a detectable amount of Venusian phosphine was present. So if the gas was produced a long time ago, it shouldn’t still be detectable. 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 … Venus phosphine find: Unexplained gas hints at potential for alien life. A gas present on Earth which is called phosphine, has been detected in the atmosphere of Venus, hinting towards unknown processes occurring on the planet, suggests a study authored by Cardiff University professor Jane Greaves and her colleagues which was published in the journal Nature Astronomy. Phosphine gas detected in the clouds of Venus could be a sign of life or some strange unknown chemistry, Lisa Grossman reported in “Possible sign of life is found on Venus” (SN: 10/10/20 & … Venus has roughly the same mass and size as Earth, so, from far away, the neighboring planet might look like a habitable world (SN: 10/4/19). or, by Matt Williams, Universe Today. “So now I hear about this, and I’m delighted,” he says. Venus is a known natural radio emitter, and phosphine creates a characteristic “dip” in that emission due to its presence. Today, our mission remains the same: to empower people to evaluate the news and the world around them. Click here to sign in with Our nearest neighbor, Venus, has cloud decks that are temperate but hyper-acidic. Along with their colleagues, the two scientists continued to probe the idea. The paper is Greaves et al., “Phosphine gas in the cloud decks of Venus,” Nature Astronomy 14 September 2020 . Mais cette observation est ensuite contestée, notamment en raison d'erreurs de calibration du télescope [19]. All rights reserved. Nature Astronomy. The information you enter will appear in your e-mail message and is not retained by Phys.org in any form. Chimie. In September, an international team announced that they had discovered phosphine gas (PH3) in the atmosphere of Venus based on data obtained by the Atacama Millimeter-submillimeter Array (ALMA) in Chile and the James Clerk Maxwell Telescope (JCMT) in Hawaii. An image of Venus, made with data recorded by Japan’s Akatsuki spacecraft in 2016. Phosphine (PH 3) is found here on Earth, as well as on the Solar System’s gas giants. Jane Greaves, who led the discovery team (and is an astronomer at Cardiff University, U.K.), claims that they were motivated to reexamine their original conclusions because the original ALMA data contained a "spurious signal" that could have thrown off their results. Here's why the latest discovery by astronomers has triggered excitement. Phosphine has also been detected in the temperate zone of Venus' atmosphere (approximately 50 km (31 mi) altitude) at 20 ppb, a concentration which is not possible with known chemical processes. On Earth, this gas is only made industrially or by microbes that thrive in oxygen-free environments. The MIT paper is Bains et al., “Phosphine on Venus Cannot be Explained by Conventional Processes,” submitted to Astrobiology – Special Collection: Venus . Published in . The chemical structure of phosphine according to Wikipedia.. Is there life on Venus? But the signature of phosphine — seen as a dip in the spectrum of light at about 1.12 millimeters — was still there. On Venus, it could suggest the presence of … Astronomers have speculated for decades that high clouds on Venus could She has a degree in astronomy from Cornell University and a graduate certificate in science writing from University of California, Santa Cruz. Phosphine gas was first detected on Venus in 2017 by Jane Greaves, an astrobiologist and professor of astronomy at the University of Cardiff in Wales and the lead author of the new study. We report the apparent presence of phosphine (PH3) gas in Venusian atmosphere, where any phosphorus should be in oxidized forms. An announcement by an international team of astronomers about the discovery of phosphine gas in the atmosphere of Venus on Monday triggered global excitement about the possibility of the presence of lifeforms on the neighbouring planet. A team of international scientists have detected traces of phosphine gas in the atmosphere of Venus. C. Sousa-Silva et al. According to Greaves and her colleagues, the ALMA data demonstrated a spectral signature that cannot be explained by anything other than the compound phosphene. This, they claim, is further bolstered by the JCMT spectra that indicated the chemical fingerprints of phosphine. Whether this compound exists there or not, Venus is still a bundle of mysteries just waiting to be solved! Astrobiology. These levels, they indicate, likely peak at five parts per billion (ppm) and vary over time and depending on location. part may be reproduced without the written permission. A false-color image shows what Venus looks like at ultraviolet and infrared wavelengths. “Not because I want to declare victory and say this is definite evidence of life on Venus.

Their revised findings were also presented at a meeting of the Venus Exploration Analysis Group (VEXAG), a NASA community forum, that took place on November 17. But surprisingly, the clouds seem to contain phosphine, a potential sign of life. The chemistry is alien, but “that’s a hospitable environment for life.”. Alcatur. PH 3 should not exist or be produced at the measured levels in an oxidized planetary atmosphere like Venus’. Therefore, there might be possibility of some unknown chemical reaction occurring on Venus atmosphere producing phosphine gas. In September, an international team of … “It’s a horrific molecule. But it’s good science at work. The news was met with its fair share of skepticism and controversy since phosphine is considered a possible indication of life (AKA a biosignature). Signs of phosphine on Venus can’t be easily explained without life. It’s not. “We’re not saying it’s life,” says astronomer Jane Greaves of Cardiff University in Wales.

But up close, Venus is a scorching hellscape with sulfuric acid rain and crushing atmospheric pressures. googletag.cmd.push(function() { googletag.display('div-gpt-ad-1449240174198-2'); }); Shortly thereafter, a series of papers was published that questioned the observations and conclusions, with one team going as far as to say there was "no phosphine" in Venus's atmosphere at all. Life on Venus? Top coverage. Phosphine Gas in the Cloud Decks of Venus ... of order parts-per-billion on Venus, comparable to phosphine production of some anaerobic Earth ecosystems10. Basically he thinks that the phosphine gas comes from chemical reactions in the atmosphere instead of actual life but he isn't discounting the possibility of life on Venus. A team of Astronomers from Cardiff University and MIT announced today the discovery of finding a rare molecule, phosphine, in the clouds of Venus. If the discovery holds up, and if no other explanations for the gas are found, then the hellish planet next door could be the first to yield signs of extraterrestrial life — though those are very big ifs.
