Exobiology: Laying the Groundwork in a Search for Extrasolar Life Michael Meyer, Exobiology Program, NASA Headquarters How did life begin, both here and perhaps elsewhere? Are we alone, a chemical fluke, or are we the result of a process common in the universe? Prior to this century the question of our origin has been relatively unconstrained. With knowledge gained through experimentation and space science - about Earth, the solar system, and the universe - the question of our origins has become a serious scientific quest. Exobiology, the study of the origin, evolution, and distribution of life in the universe, embodies this quest. With the recognition that: chemical evolution proceeded rapidly to life on Earth, life may be a natural consequence of planetary evolution, and planetary systems may be common in the universe, life is likely to be common in the universe. How can we find it? With modeling, observation, and sampling in our solar system, we can learn of the planets' evolution through time. What is the relative importance of distance from the sun, bulk composition, and mass that determine whether the planetary body could have ever sustained life. What planetary bodies are the better candidates for life around other stars? What are the potential signatures for life? So far, we have only one example, rather evolved life at that. How would Earth's biosphere appear from space? Technology has an obvious signature but technology has been here for an extremely limited period of time. For the last 2 billion years, Earth's biosphere has been dominated by oxygenic photosynthesis - ozone would be an indicator. Chemical disequilibria are maintained by biology and could be indicative of life, for example methane or nitrous oxide in the presence of oxygen. But what of early Earth? What combination of reduced species would be indicative of life in a reducing atmosphere? Perhaps Earth's atmosphere was dominated by volcanic activity during its first 1.5 billion years, swamping any biological signature. An alternative maybe to search for a predominance of an optically active pigment, like chlorophyll or rhodopsin.

Extreme Environments on Earth: Analogs for Exobiology Faculty: Baross, Delaney, Deming, Frederickson, Gammon, Leigh, Rodrigo, Staley Background Our basic premise is that life on Earth is the best model we have for life elsewhere. Life here is extraordinarily adaptable: organisms thrive in extremes of temperature, pressure, pH, solute concentrations, dryness, ionizing radiation, and other conditions. Study of life in extreme environments on Earth guides the search for extraterrestrial life. We study Earth's "extremophiles", organisms (especially microbes) that live in the most extreme conditions, both to identify the extreme limits of Earth-like life, and to learn to identify the types and activities of those life forms. Starting Assumptions and General Hypotheses Liquid Water Assuming water is required for organisms' activity and growth, limits of microbial life can largely be defined by the boundary conditions for liquid water. Salinity and hydrostatic pressure determine phase changes: different combinations can expand the "liquid" boundaries substantially, especially at high temperatures.

Recent research in "life sciences" have strongly increased our knowledge in the processes of prebiotic evolution. The current field is divided into three parts that emphasise the main steps in the evolution of life in the universe: The formation of the extraterrestrial organic matter and the subsequent delivery to the early Earth. The formation of the first structures that resemble living cells as we know them. The evolution of these cells to modern organisms.

75. Astrobiology/Exobiology Education Note As more college courses are planned in astrobiology exobiology, it is useful to share information about course content and the feedback we receive from http://www.issol.org/educationtext.html

Astrobiology/Exobiology Education Note Following for your information is preliminary text information for undergraduate introductory courses in astrobiology "Astrobio 101". The first three are rather comprehensive, while the next three are more focused on the origin of life on Earth. I also list several recent trade books in astrobiology or related fields that are sometimes used as supplementary reading for undergraduates. I would be interested to know if you have used any of these books, and if so what success you have had with them.

Searching for Life in the Solar System ... And Beyond A Research Discussion Meeting London, UK - 31 October 1996 THE NASA EXBIOLOGY PROGRAMME David J DesMarais, NASA Ames Research Center NASA will indeed conduct a more active search for life beyond Earth. Research on the Martian meteorites will be augmented by $2 million to contributed equally by NASA and NSF. The science strategy for the NASA Mars Surveyor Program now places a much higher priority on the search for evidence of life, particularly fossil evidence. This program features two launches per opportunity (every two years, starting this November). The focus on Exobiology emphasises high resolution multispectral orbital mapping to locate key aqueous sedimentary minerals, the exploration of ancient terrains by capable rovers, and the need for multiple sample return missions. A meeting will be held November 12-14 to plan a program to explore potential subsurface oceans on Europa. This past June, Ames Research Center hosted the "Blue Dot Workshop - Spectroscopic Search for Life on Extrasolar Planets". The Workshops emphasised the biogeochemistry of gases, the chemistry of spectroscopy of planetary atmospheres, and the remote sensing of planetary atmospheres and surfaces. In particular, the Workshop addressed definitive biological indicators of life in addition to the presence of abundant free oxygen and ozone. Incidentally, two spacecraft relevant to the search have been conceptualised. The "Kepler" craft could detect stellar occultations by earth-sized planets in other solar systems. "The Planet Finder" could additionally perform analyses of extrasolar planetary atmospheres.

Topic:Exobiology From Wikiversity Jump to: navigation search Welcome to the Wikiversity Center for Exobilogy, part of the School of Biology How common are the conditions required for life? Exobiology , also known as xenobiology or astrobiology is a speculative field within biology concerned with extraterrestrial life. The Center for Exobiology is a Wikiversity content development project where participants create, organize and develop learning resources about the search for life beyond Earth. Contents Where are the data? Possible data Learning resources References ... edit Where are the data? Terrestrial Planet Finder. Astrobiology is an idea in search of data. Many scientists expect that life is common, probably having come into existence on millions of planets. However, astrobiology is a speculative field within biology; nobody has evidence for extraterrestrial life. Astrobiology includes the concept of artificial life, since any life form with human-like intelligence could conceivably create artificial life in a laboratory. Such artificial life might be more suitable than a biological organism for interstellar travel. While currently funded efforts in astrobiology focus on planetary exploration and attempts to detect planets with Earth-like atmospheres, it has been suggested that we should also look closely at Earth for signs that alien artificial life is already here. edit Possible data Search for life on Mars Liquid water on Europa edit Learning resources The Drake Equation can human like intelligence evolve under water?
