Conferences and Workshops Seminars focus on collaborative technologies has enabled a unique phenomenon to emerge: the Workshop Without Walls. This structure brings together scientists from across the astrobiology community in a focused environment combining presentations with rich discussion. Seminarsen-usSat, 06 Jun 2020 05:25:21 +0000Environments of Terrestrial Planets Under the Young Sun: Seeds of Biomolecules "Environments of Terrestrial Planets Under the Young Sun: Seeds of Biomolecules" Symposium was held on April 9-13, 2018, hosted by the Sellers Exoplanet Environments Collaboration at NASA Goddard Space Flight Center, Greenbelt, MD, USA. This symposium was a major international interdisciplinary conference in the emerging area of astrobiology covering astrophysical, physico-chemical, atmospheric and geological aspects of environments of early terrestrial planets with a focus on the impacts of the young Sun’s space weather on the precursors of life. This workshop drew on the format of the highly successful prior workshop "Exoplanetary Space Weather, Climate and Habitability" (held in New Orleans, LA in 2016) in that practitioners were asked to discuss challenges around the fundamental questions of precursors and building blocks of life. *Day 1: Monday, April 9, 2018 - Space Weather from The Young Sun and Active Stars* Building 34, Room W150 Session Chair: Nat Gopalswamy (GSFC) <a href="">9:00 - 9:30 am Opening talks by V.

Rochelle Gateway Center (MHRGC) in Laramie, Wyoming. The field of exoplanets is currently at the cusp of a watershed moment in finding life on other worlds, propelled by the discoveries of habitable zone terrestrial planets in both ground and space-based surveys, and the potential for future telescopes to characterize the atmospheres of some of these rocky planets. Preparing for such a singular moment needs a diverse community, including Earth scientists, heliophysicists, planetary scientists, and astrophysicists. Following the goals of NExSS to investigate the diversity of exoplanets and to learn how their history, geology, and climate interact to create the conditions for life, and corresponding biosignature detection, the workshop aims to address these questions: What does it mean to be habitable? What conditions are needed for habitability and how do those conditions arise? What are the indicators of these conditions and their histories? How can we observe these indicators? "Click here for the official conference website": "Click here to watch the live webcast": 2017 2017 is the next in a series of conferences organized by the astrobiology community. The theme for AbSciCon 2017 is “Diverse Life and its Detection on Different Worlds.” Mars and icy worlds in our solar system are increasingly recognized as habitable, even as increasing numbers of exoplanets in their stars’ habitable zones have been discovered. The focus is shifting from identification of habitable worlds, to detection of life on them. <iframe width="492" height="277" src="" frameborder="0" allowfullscreen></iframe> Click "here": for the full conference program. Among other topics, the conference will address: Setting the Stage for Geochemistry Setting the Stage for Biochemistry Biomarkers of Life in Anaerobic Ecosystems and Different Evolutionary Stages Biomarkers of Anaerobic Ecosystems Biogeochemical Cycles on Water Worlds Near and Far Biosignatures on Exoplanets Preparing for Life Detection: Astrobiology Education and Public Outreach ELSI International Symposium VIEWS ON THE EMERGENCE OF THE BIOSPHERE <iframe width="492" height="277" src="" frameborder="0" allowfullscreen></iframe> The emergence of biosphere on Earth, and possibly elsewhere in the universe, remains one of the great unsolved scientific questions. Research into the origin and subsequent evolution of life takes place across an array of scientific disciplines, including but not limited to planetary sciences, astronomy, theoretical physics, chemistry and biology. The goal of the Symposium is to provide a forum for diverse perspectives and unify the fragmentary knowledge stemming from a single discipline. Accordingly, the program features talks and discussions aimed at understanding the nature of life, constraints of habitability, early Earth environments, systems chemistry, structure and attributes of early life. The Symposium will gather eminent investigators as well as provide opportunities for early-career scientists to present their findings in a poster format and exchange ideas in discussion sessions.

New Orleans, LA, and other virtual locations.* "Click here to RSVP if you wish to attend remotely to help us better organize this upcoming workshop. No commitment necessary!": "Click here for the latest agenda.": "Click here for information on how to participate remotely.": Organizers: Vladimir Airapetian (NASA GSFC), William Danchi (NASA GSFC) The landscape of exoplanetary science has changed considerably with the great success of the Kepler mission, which has discovered thousands of transit candidates and hundreds of confirmed exoplanets around K-M dwarf stars and a few planets within their Habitable Zones (HZs). How does the classic definition of the HZ relate to the conditions required for development and support of life as we know it within “biogenic zones”? Kepler also revealed thousands of superflares on hundreds of solar-type stars, which may suggest that host stars have profound effects on the physical and chemical evolution of exoplanetary atmospheres. What do we know about the impact of space weather on our own planet? How can we use lessons learned from the largest solar space weather events to understand how exoplanets are affected by their host stars? Stellar forcing in the form of XUV fluxes, winds, coronal mass ejections (CMEs) and associated energetic particle events (EPE) can have a dramatic effect on the histories of atmospheric loss, atmospheric chemistry, and climates that shape exoplanetary habitability. Thus, there is a need to perform sophisticated observations and develop theoretical models to characterize the forms of magnetic activity, their effects on exoplanetary space weather, and its effects on atmospheric dynamics, chemistry and habitability conditions. The assessment of the impacts of host stars on the climate and habitability of terrestrial (exo)planets may significantly modify the current definition of the habitable zone and provide new avenues for searching for signatures of life. The major goal of the workshop is to promote collaboration between NExSS team members and the broader U.S. and international communities, to discuss recent progress in interdisciplinary studies, and to develop a community roadmap that crosess the boundaries of space weather from the Sun to cool stars and investigates its impact on (exo)planetary climates. This will be achieved by bringing together scientists involved in related activities in the broader astrophysics, heliophysics and planetary science communities. Their perspectives of interrelations among space weather, climate and habitability conditions will be crucial in defining the boundaries of habitability of exoplanets around F to M dwarfs. The workshop will be open to community virtual participation via Adobe Connect. *The following key themes will be reviewed and discussed:* _How do solar and stellar explosive events and associated space weather (SW) form?_ _How can we search for SW signatures around cool dwarf stars at various phases of evolution?_ _What is the impact of space weather on the rate of atmospheric escape from magnetically shielded and unshielded (exo)planets?_ _What lessons on atmospheric escape rates can we learn from Earth, Mars and Venus?_ _How does space weather (XUV, particle radiation and interplanetary magnetic fields) affect water loss from (exo)planets?_ _How does space weather impact planetary chemistry and climates?_ _What are the SW effects imposed by cool stars on planetary surface habitability?_ _What are the SW imposed spectral signatures from (exo) planetary atmospheres?_ The major output of the workshop will be the development of three white papers (one per science topic) aimed at specifying a conceptual framework for the ways forward in theoretical modeling, chemical experiments, and in situ and remote observations of bio-signatures of life affected by SW. The outcome of such an interdisciplinary approach will become crucial in defining the candidates for habitable planets for upcoming exoplanetary missions including TESS and JWST and for a potential future direct imaging mission. Workshop: Requirements for Origin of Life Field Investigations*Invited Speakers* Laurie Barge Pablo Sobron Eugenio Simoncini Kirt Robinson Julyan Cartwright Jan Amend Blair Thornton (U Tokyo) Ken Takai (JAMSTEC) Roy Price Darlene Lim Adam Monroe "Workshop Website": | "Workshop Program": One objective of the NASA Astrobiology Institute's "Thermodynamics, Disequilibrium, Evolution" (TDE) focus group is to understand how geochemical disequilibria are generated and how these gradients could have been harnessed to drive early metabolic systems. Studies of different types of hydrothermal vent systems have revolutionized our understanding of how metabolism and energy conversion on Earth might have emerged from a geological setting, and also have advanced our knowledge of possible environments where life could exist on other wet rocky worlds. Past TDE workshops have advanced our knowledge of laboratory simulations and models of far-from-equilibrium systems relevant to the origin of life. To advance this knowledge even further and to prepare for the exploration of potential habitable environments on other worlds, there is a need for new, innovative in situ exploration technologies and analytical methods. The goals of this workshop are: to define laboratory and analytical requirements for simulating seafloor settings on early Earth and other worlds, and to identify new technologies and operational strategies for the in-situ exploration of energetically active field sites that may represent analogs for environments in which life emerged. The 3-day workshop will gather experts in planetary disequilibrium and origin of life, ocean sciences, experimental design and sensing technologies. 2016 atmospheres from Earth to exoplanets, M-dwarfs as host stars, M-dwarf planet atmospheres, direct imaging, hot Jupiters, aerosols and clouds, early Earth, surface-atmosphere interactions, volatile delivery and loss. <b><u>Archived Presentations:</u></b> *Monday, August 1st, 2016* Andy Ingersoll (Caltech) "[view presentation]": Jonathan Fortney (UC Santa Cruz) "[view presentation]": Ralph Lorenz (NASA GSFC) "[view presentation]": Heather Knutson (Caltech) "[view presentation]": Jayne Birkby (Harvard University) "[view presentation]": Y.

The aim of the workshop is to discuss about chemical disequilibrium and its link to planetary habitability. In particular, the Thermodynamics, Disequilibrium and Evolution focus group seeks to understand how disequilibria are generated in geological / chemical / biological systems, and how these disequilibria can lead to emergent phenomena, such as self-organization and eventually, metabolism. The prospects for planetary atmosphere characterization are excellent with access to large an amount of data for different kind of stars either with ground- or space-based telescopes supported by accurate modeling of the atmospheric compositions and their corresponding spectra. In particular for many discovered exoplanets (hot and gaseous), a large chemical disequilibrium in the atmosphere has been observed, due to the high vertical temperature gradient. Several new studies are now comparing this of vertical-mixing driven disequilibrium with the chemical disequilibrium characterizing the atmosphere of planet Earth, which is mainly due to the presence of life. However, present research on exoplanet's atmospheric disequilibrium is focused on a very small number of compounds (CH4, CO, CO2, H2O), lacking for a generalized and wider methodology. In this workshop we plan to enlarge these studies to a joint effort between the thermodynamics of habitable conditions to the exoplanetary atmospheres. The workshop at the Observatory of Côte d'Azur (OCA) is the main opportunity in Europe in 2015 to discuss about the connection between planetary habitability and its atmospheric disequilibrium, through the use of some thermodynamic functions. OCA has a long tradition in the field of theoretical planetology. The reasearch are focused on the detection and study of extra-solar planets, protoplanetary disks, and on the formation and evolution of planetary systems. This will ensure an excellent context for local exchanges. Three principal topics will be tackled during the workshop: 1. Icy moons, icy planets and the conditions for the emergence of life. 2. The modeling and observations of exoplanetary atmospheres: chemistry and physics. 3. The chemical disequilibrium in planetary atmospheres: from hot Jupiters to habitable planets. The Thermodynamic, Disequilibrium and Evolution (TDE) Focus Group is a NASA Astrobiology Institute (NAI) sponsored project aimed to make researchers meet and discuss on the thermodynamic requirements of life emergence and planetary habitability. In particular, since its set up in 2011, the TDE helped in bridging the gap between researchers working on the theory and experimental aspects of the Origin of Life and astronomers. It provided a thermodynamic discussion board for planning future space missions and deciding on future targets for the search for habitability. The TDE concentrates on the entropy and energy requirements for life and planets and how they inform our selection of potentially habitable planets and environments in the cosmos. The TDE page on the "NAI website": The TDE Focus Group meets twice per year. Since its establishment in 2011, there have been six workshops: Madrid (Spain), Florence (Italy), Atlanta (USA), Granada (Spain), Phoenix (USA), Florence again, Campinas (Brazil) and Tokyo (Japan). 2015 Astrobiology Science Conference 2015 (AbSciCon 2015) is the next in a series of conferences organized by the astrobiology community. The conference convened scientists from all over the world who work in the interdisciplinary field of astrobiology — the study of the origin, evolution, distribution, and future of life in the universe — to report on research findings and plan future endeavors. The theme for AbSciCon 2015 was “Habitability, Habitable Worlds, and Life.” Please check "AbSciCon's website": for more details. *Monday, June 15th* Plenary Sessions: 8:00 a.m. "Opening Remarks": 8:15 a.m. _The Deep History of a Carbon Atom_ "Michael Callahan": "Andrew Steele": "Karen Meech": 9:15 a.m. _Sustained Habitability on a Dynamic Early Earth_ "James Kasting": "Panel Discussion": 10:30 a.m. _The Beginning and End of the RNA World from the Perspective of Ribosome Origins_ "Harold Bernhardt": "James Stephenson": "Anton Petrov": "G.
