When Mogul's team reexamined the LNMS data from Venus' lower and middle clouds (a potentially habitable zone on the planet), they found signals that look a good deal like phosphine, the researchers wrote. Mogul suspects that in the initial analysis of the LNMS data performed in the 1980s, scientists prioritized those molecules already thought to exist in the Venusian atmosphere. Venus also is a planetary destination we can reach with smaller missions. Two of the next four candidate missions for NASA’s Discovery Program are focused on Venus, as is Europe’s EnVision mission, in which NASA is a partner. The possibility of life on Venus is a subject of interest in astrobiology due to its proximity and similarities to Earth.To date, no definitive proof has been found of past or present life on Venus.Theories have decreased significantly since the early 1960s, when spacecraft began studying the planet and it became clear that its … A NASA Probe May Have Found Signs of Life on Venus 40 Years Ago. Jennifer Chu archive page; December 18, 2020. This discovery was a breakthrough as it suggested that life could thrive in the extreme temperatures of Venus. The discovery is not yet peer-reviewed and doesn't really add much detail we don't already know to the 'life on Venus' story, but it does somewhat solidify the recently-reported discovery. But there's reason to require the concept seriously. An image shows how Pioneer-13's Large Probe, which carried the LNMS, may need to look at because it plunged through Venus's clouds. When scientists first described the LNMS leads to the 1970s, they didn't discuss phosphorus-based compounds like phosphine, focusing instead on other chemicals. Researchers claim simple microbial life forms might exist in the upper atmosphere of the world dubbed Earth’s evil tw… The search for life elsewhere in the solar system has until now not focused on Venus. ‘Life on Venus’ plot thickens as new discovery suggests NASA may have found life-indicating gas in 1978, they just forgot There are no known natural processes that might explain the volume of the gas found -ed.]. NASA found the clues to life on Venus almost four decades ago but never realized it. Not everyone is convinced. If life does exist on Venus, NASA may have first detected it back in 1978. Sousa-Silva is currently looking through old infrared telescope observations of Venus, hunting for additional overlooked evidence of phosphine. Venus: The Basics Venus is a dim world of intense heat and volcanic activity. “People discounted [these molecules] because they thought there was no way” they were present in the atmosphere, Mogul says. But, just maybe, the clinching evidence will actually come from Earthly archives of missions past, where it has been awaiting recognition for nearly a half-century. High in the toxic atmosphere of the planet Venus, astronomers on Earth have discovered signs of what might be life. We understand life as it exists here on Earth, but life on Venus could be something really at odds with everything we know. Unfortunately, although a physical copy of this information is stored in the NASA Space Science Data Coordinated Archive (NSSDCA) at NASA’s Goddard Space Flight Center, access to the archive is currently restricted because of COVID-19. Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at, atmospheric probes that can directly sniff out the gas, evidence suggests the presence of phosphine, Alien Hunters Discover Mysterious Signal from Proxima Centauri, Asteroid Dust from Hayabusa2 Could Solve a Mystery of Planet Creation, Fresh Data from Gaia Galaxy Survey Gives Best Map Ever of the Milky Way. (A "fully oxidizing environment" wouldn't include phosphine or most other chemicals seen as signs of life.). A probe that was sent to Venus back in 1978 returned readings that showed the presence of … "When the [Nature Astronomy paper] came out, I immediately thought of the legacy mass spectra," Mogul told Live Science. The apparent discovery of phosphine in the Venusian atmosphere has been both widely heralded and greeted with caution. 1 Back to Venus: Rocket Lab looks to beat NASA in search for life on Venus, other worlds. Meet NASA's latest Mars Rover: Will Perseverance find life in 2021? 2020 in review: The hunt for life on Venus continues. "We believe this to be a sign of chemistries not yet discovered," they wrote, "and/or chemistries potentially favorable always.". Space breakthrough: Life on Venus 'first detected 42 years ago' SPACE scientists first detected signs of alien life on Venus in 1978, archived NASA data suggests. 2 Could aliens be living on Venus? But Pioneer 13's sample did have evidence of some molecule present within the gas that had the identical mass as phosphine — in amounts that match the amount described within the Nature Astronomy paper. Several spacecraft are set to fly past Venus soon: Europe and Japan’s BepiColombo spacecraft, NASA’s Parker Solar Probe and Europe’s Solar Orbiter. Life on Venus? Although the space agency has ignored Venus since its Magellan mission in the 1990s that mapped its surface, NASA now has … VERITAS (Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy) – this spacecraft would orbit Venus and map its surface with radar. Many experts believe the best chance of verifying Venusian phosphine lies in atmospheric probes that can directly sniff out the gas. By Paul Voosen Nov. 17, 2020 , 2:50 PM. On Sept. 14, a team of scientists made a bombshell announcement within the journal Nature Astronomy: Using telescopes, they'd detected phosphine, a toxic gas long proposed as a possible sign of alien microbial life, within the upper a part of the planet's thick atmosphere. Life on Venus continues to be an extended shot. ESO/M. If Mogul and his colleagues have correctly interpreted the Pioneer data, Zolotov says, “we’d expect a much higher concentration of phosphine than measured by astronomers, which is also a red flag.”. Yuri Milner, the founder of Russia’s Mail.ru (Russia’s equivalent of Yahoo), announced that his organization, Breakthrough Initiatives, would be funding research to study the possibility of life in Venus’ clouds. Upon hearing the news, Mogul and his co-authors went back to the studies released decades ago following the 1978 Pioneer 13 mission. With luck, we may be able to start on it this week.”, Other archived data could prove useful, too. Pioneer 13 dropped an oversized probe (the LNMS) into Venus' clouds; suspended from a parachute, the probe collected data and beamed it back to Earth because it plummeted toward its robotic death. This has relevance for assessing the exobiological potential of extrasolar Venus-like greenhouse planets. After speeding through space for 123 days, NASA’s Pioneer Venus 2 mission finally reaches its destination: Venus. Potential signs of life on Venus are fading as astronomers downgrade their original claims. The discovery of phosphine, a byproduct of anaerobic biology, is the most significant development yet in building the case for life off Earth. Now the spacecraft makes its … In fact, NASA in July launched a next-generation rover to look for traces of potential past life on Mars. Day: About 243 Earth days. LNMS wasn't built to hunt phosphine-like compounds and would have had a tough time distinguishing the gas from other molecules that have similar masses. (Image: © NASA) If life does exist on Venus, NASA may have first detected it back in 1978. While efforts to confirm the finding via observations from Earth or even fortuitously planned spacecraft flybys are underway, archived data from a decades-old NASA mission to Venus may have been hiding much sought-after verification in plain sight—with potentially more revelations to come. 2020 in review: The hunt for life on Venus continues Image of fairy penguins watching Melbourne lights wins photo prize Another group reached decades into the past and found a potential signal for phosphine, buried in data from a NASA mission that started studying Venus in 1978. But the finding went unnoticed for 42 years. An unexpected discovery in the clouds of Venus has scientists buzzing. The discovery, published to the arXiv database Sept. 22 and not yet peer-reviewed, doesn't tell researchers much beyond what was reported in Nature Astronomy — though it does make the presence of phosphine (made of a phosphorus atom and three hydrogens) even more certain, they said. Although Venus is easier to reach than Mars, scientists and space agencies around the world show little interest in exploring the planet. The probe, however, actually took data from an altitude of 90 kilometers all the way down to the surface of the planet. by . Life on Venus is still a long shot. 6 "I believe that evidence for [trace chemicals that would be signatures of life] within the legacy data was a form of discounted because it absolutely was thought that they might not exist within the atmosphere," Mogul said. by . Life on Venus? “We were able to extract some data from the literature from about 40 years ago,” says Mogul, whose team recently posted its findings on the preprint server arXiv.org. The planet Venus in a composite of data from NASA's Magellan spacecraft and Pioneer Venus Orbiter. Venus was the first planet ever visited by a spacecraft, when NASA's Mariner 2 flew by in 1962. Researchers poring over archives from previous missions to Venus claim that NASA may have first detected phosphine signatures (indicating potential microbial life) back in 1978, and they just went unnoticed for the past 42 years. This has relevance for assessing the exobiological potential of extrasolar Venus-like greenhouse planets. "It's tremendously exciting," said David Grinspoon, senior scientist at the Planetary Science Institute. Rocket Lab's plan to search for life on Venus in 2023 just got more exciting By Mike Wall 16 September 2020 The 2023 life-hunting mission will be just the beginning, if all goes according to plan. Venus phosphine find: Unexplained gas hints at potential for alien life. What's needed, they wrote, is further, sustained exploration of Venus. Astrobiology is the study of the origin, evolution, and distraction of life … Distance from the sun: About 67 million miles, about 3/4 as far as the Earth is from the sun. How Sea Butterflies Zip Through the Water, Russia Approves 'Sputnik V' Covid-19 Vaccine, 'Naked' shark was born without skin or teeth in world first, Vikings may not have been blonde, or Scandinavian, First Evidence of Ancient Egyptian Head Cones, Tiny Virus-eaters Might Lurk In the Ocean. "We need a more sustained approach for exploration like that of Mars," Mogul said. To double-check the detection, scientists are eager for more data, either from large telescopes or entirely new interplanetary missions. "I think many of us are now revisiting the notion of Venus as a completely oxidizing environment." On Sept. 14, a team of scientists made a bombshell announcement within the journal Nature Astronomy: Using telescopes, they'd detected phosphine, a toxic gas long proposed as a possible sign of alien microbial life, within the upper a part of the planet's thick atmosphere. Instruments such as the LNMS identify molecules by measuring their speed as they impact a detector, enabling their mass to be calculated. Life on Venus continues to be an extended shot. Kornmesser & Nasa/JPL/Caltech. Credits: NASA. This is something we never thought possible. Year: About 225 Earth days. As such, after consulting with my co-authors, we identified the initial scientific articles, and promptly started searching for phosphorous compounds.". Similar in structure and size to Earth, Venus' thick, toxic atmosphere traps heat in a runaway 'greenhouse effect.' High in the toxic atmosphere of the planet Venus, astronomers on Earth have discovered signs of what might be life. 2020 in review: The hunt for life on Venus continues Image of fairy penguins watching Melbourne lights wins photo prize And the atmosphere is heavily composed of sulfuric acid, which blocks out the Sun and leads to acid rainstorms on the surface of the planet. A fundamental question in exobiology remains the degree to which habitats on Venus, past and present, were, or are suitable for life. NASA and also the European, Indian and Russian space agencies have plans for Venus probes that may be helpful, he said. Life on Venus continues to be an extended shot. Another group reached decades into the past and found a potential signal for phosphine, buried in data from a NASA mission that started studying Venus in 1978.
