We can get into this later on in the episode. 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. “Clearly something has gone wrong, very wrong, with Venus. Seager likewise cautioned it’s too early to conclude there’s life on the planet based on these results alone. Dr. Seager noted that Venus is known to have a layer of haze. But how do we find out for sure?! 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. NASA has two Venus missions currently under review. 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. Book Sara as a Guest Speaker. “We are not claiming that we have found life on Venus,” said Sara Seager of MIT, also part of the discovery team. 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. Se la “We are not claiming we have found life on Venus,” she 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. The field of exoplanets is maturing but still with huge unrealized potential. We need to GO there. (Credit: Royal Astronomical Society) Venus is often called Earth’s sister planet. 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. Study co-author Sara Seager, an MIT planetary scientist, ... Venus is kind of Earth’s evil twin,” Clements said. 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. "While the surface conditions of Venus make the hypothesis of life there implausible, the clouds of Venus are a different story altogether." Sara Seager is an astrophysicist and planetary scientist at MIT. 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. "We are claiming the confident detection of … Sara Seager – MIT – Principal Investigator; Janusz … Professor Sara Seager is a planetary scientist and astrophysicist. Biosignature expert Sara Seager will lead the study team. It could take years or even decades to prove conclusively whether there is life in the Venusian clouds, Seager said. Comments (4) Japan's Akatsuki spacecraft captured this false-color image of Venus' dayside on March 30, 2018. If phosphine turns out not to be present, this pathway evaporates as a viable life-on-Venus scenario. “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. https://astronomycommunity.nature.com/users/394517-sara-seager “I went to Jarvis Collegiate and I used to walk through campus on my way because it was so beautiful,” says Seager, a professor […] But all of this will take time. “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. I’m totally going to do a video about that. Co-author Sara Seager says astronomers tried to figure out other, non-biological ways it could be produced but came up empty. The temperate, habitable layer of Venus’ atmosphere as presented by Professor Sara Seager on 14 September 2020. We haven’t explored Venus for a very long 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. And so, I put it on my list of videos. di ricerca, coordinato da Sara Seager, professoressa di scienze planetarie, fisica e ingegneria aerospaziale presso il Massachusetts Institute of Technology (MIT). 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. 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. She has been a pioneer in the vast and unknown world of exoplanets, planets that orbit stars other than the sun. Sara Seager, a fellow MIT scientist who studies exoplanet atmospheres, agreed, saying "we are not claiming we have found life on Venus." 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 was like, oh, that’s such a cool idea. Airborne life on Venus would be unusual, but perhaps not as strange one might think. 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. So, Venus might have life! But, she added, “on Earth, phosphine is only associated with life.” "We exhaustively went through every possibility and ruled all of them out. -- 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. Sara Seager Well, we don’t have infinite resources, unfortunately, but it sure would be nice to see more spent on Venus. Venus does have an impressive, permanent cloud deck, stretching for over 20 km in vertical height. 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. Just last month, inspired by the upcoming phosphine findings, MIT astronomer Sara Seager … No life of any kind could exist on the Venusian surface. Rocket Lab's Venus plans were in the works long before the company started talking to Seager and her colleagues, Beck said. “I can’t overemphasise how fringe the whole idea of life on Venus was,” the astronomer Sara Seager said.
