I think that life in Venus' clouds today is so unlikely that we'll find other chemical pathways of creating phosphine in the atmosphere ... ," said team-member Prof Sara Seager from MIT. Sara Seager, a fellow MIT scientist who studies exoplanet atmospheres, agreed, saying "we are not claiming we have found life on Venus." di ricerca, coordinato da Sara Seager, professoressa di scienze planetarie, fisica e ingegneria aerospaziale presso il Massachusetts Institute of Technology (MIT). Just last month, inspired by the upcoming phosphine findings, MIT astronomer Sara Seager … (Credit: Royal Astronomical Society) NASA has two Venus missions currently under review. We haven’t explored Venus for a very long time. It could take years or even decades to prove conclusively whether there is life in the Venusian clouds, Seager said. Professor Sara Seager’s fascinating and thought-provoking talks explain, in layman’s terms, the exciting field of exoplanet research and the holy grail to find and identify an Earth-type planet. Seager likewise cautioned it’s too early to conclude there’s life on the planet based on these results alone. Co-author Sara Seager says astronomers tried to figure out other, non-biological ways it could be produced but came up empty. Now a pioneering astrophysicist who made headlines for the possible discovery of life on Venus, Sara Seager stumbled upon her path to the stars while taking a shortcut across the University of Toronto’s St. George campus. https://astronomycommunity.nature.com/users/394517-sara-seager Sara Seager: It is so unexpected but I never thought in my life that it would be something we should either look for, that we would find in Venus. But all of this will take time. Questo gruppo sarà formato da astronomi, astrobiologi, chimici e ingegneri da tutto il mondo e avrà lo scopo di esaminare la possibilità che ci sia vita su Venere. Authors: Sara Seager, Janusz J. Petkowski, Peter Gao, William Bains, Noelle C. Bryan, Sukrit Ranjan, Jane Greaves Download PDF Abstract: We revisit the hypothesis that there is life in the Venusian clouds to propose a life cycle that resolves the conundrum of how life can persist aloft for hundreds of millions to billions of years. “Clearly something has gone wrong, very wrong, with Venus. I was like, oh, that’s such a cool idea. Yet, due to a massive CO 2 greenhouse atmosphere, Venus’ scorching surface temperature of 700 K means no life could ever survive at the surface. "We exhaustively went through every possibility and ruled all of them out. “I can’t overemphasise how fringe the whole idea of life on Venus was,” the astronomer Sara Seager said. Study co-author Sara Seager, an MIT planetary scientist, ... Venus is kind of Earth’s evil twin,” Clements said. Book Sara as a Guest Speaker. Biosignature expert Sara Seager will lead the study team. She has been a pioneer in the vast and unknown world of exoplanets, planets that orbit stars other than the sun. “We are not claiming that we have found life on Venus,” said Sara Seager of MIT, also part of the discovery team. Sara Seager Well, we don’t have infinite resources, unfortunately, but it sure would be nice to see more spent on Venus. "While the surface conditions of Venus make the hypothesis of life there implausible, the clouds of Venus are a different story altogether." But how do we find out for sure?! We need to GO there. If phosphine turns out not to be present, this pathway evaporates as a viable life-on-Venus scenario. Se la Professor Sara Seager is a planetary scientist and astrophysicist. Sara Seager is an astrophysicist and planetary scientist at MIT. No life of any kind could exist on the Venusian surface. Sara Seager – MIT – Principal Investigator; Janusz … . And Seager commented, “We are thrilled to push the envelope to try to understand what kind of life could exist in the very harsh Venus atmosphere and what further evidence for life a mission to Venus could search for.” Project Leadership. Rocket Lab's Venus plans were in the works long before the company started talking to Seager and her colleagues, Beck said. Venus is often called Earth’s sister planet. The temperate, habitable layer of Venus’ atmosphere as presented by Professor Sara Seager on 14 September 2020. Possible marker of life spotted on Venus Date: September 14, 2020 Source: ESO Summary: Astronomers have discovered a rare molecule -- phosphine -- in the clouds of Venus. “Venus is extremely bright, and many of the large ground-based telescopes cannot properly observe it,” says Sara Seager, an MIT astronomer and one of the coauthors of the new phosphine study. Sara Seager, una profesora de física y ciencia planetaria de MIT y miembro del equipo de investigación, lo planeta de la siguiente manera: “Podrían existir dos explicaciones: una en la que existe algún proceso químico desconocido que, de alguna manera, podría producir la fosfina. Seager's team also has been talking to the private space company Rocket Lab, which had been independently pursuing their own missions to Venus, with ambitions to launch as soon as 2023. Venus does have an impressive, permanent cloud deck, stretching for over 20 km in vertical height. -- Carl Sagan, Nature, 1967 In celebration of Carl Sagan Day 2020, the Secular Society of MIT presents a special talk by MIT professor of physics and planetary science, Sara Seager. “It’s very stable, and people don’t know what the particles there are, but they remain suspended for a very long time,” she said. But, she added, “on Earth, phosphine is only associated with life.” At the same time, he noted, the clouds of Venus consist mostly of sulfuric acid—a very harsh environment for life, at least as we know it. I’m totally going to do a video about that. “I went to Jarvis Collegiate and I used to walk through campus on my way because it was so beautiful,” says Seager, a professor […] The field of exoplanets is maturing but still with huge unrealized potential. Sara Seager and collaborators found evidence of a chemical called phosphine in the atmosphere, something that could be explained by microbes living in the clouds of Venus. Comments (4) Japan's Akatsuki spacecraft captured this false-color image of Venus' dayside on March 30, 2018. And so, I put it on my list of videos. Little did I realize Sara Seager playing three-dimensional chess here had this all cued up and ready to go for them when we got the announcement of phosphine on Venus. We can get into this later on in the episode. Dr. Seager noted that Venus is known to have a layer of haze.
