Astrobiology Astrobiology is an interdisciplinary field, combining aspects of astronomy, biology and geology, which is focused primarily on the study of the origin, distribution and evolution of life. It comes from the Greek words astron = star, bios = life and logos = word/science), and is also known as exobiology (Greek: exo = out) or xenobiology (Greek: xenos = foreign). Some major astrobiological research topics include: What is life? How did life arise on Earth? What kind of environments can life tolerate? How can we determine if life exists on other planets? How often can we expect to find complex life? What will life consist of (DNA/Carbon based? Physiology?) on other planets? Exobiology and xenobiology are terms also found in science fiction, although typically such terms refer to the speculative biology of an extraterrestrial. A xenobiologist is usually a human doctor or biologist who is expert on the physiology of alien organisms and life forms. Overview Although astrobiology is an emerging field, the question of whether life exists elsewhere in the universe is a verifiable hypothesis and thus a valid line of scientific enquiry. Astrobiology does not claim to be a pure scientific discipline in the sense of physics or biology but rather represents an effort by researchers in different disciplines to attempt answers to questions about life by drawing on knowledge of multiple scientific fields. Since we have only one example of a planet teeming with life most work is speculative, educated guesses based on fundamental laws of physics, (bio-)chemistry, and our current understanding of biology.

Links Home General information about the Graduate School in Astrobiology The graduate school in Astrobiology is based at Stockholm University and got started in September 2006. 8 graduate students were selected to embark on an interdisciplinary PhD programme. Astrobiology is a new and rapidly expanding field. It tries to find answers to questions such as: What are we actually defining as life? Where does physics and chemistry end and the evolution of life and biology begin? Which are the conditions for life to emerge on planets and remain there? Is or was life on other planets (e.g. Mars) or their satellites (e.g. Titan) possible? To which extent can building blocks of biomolecules (e.g. amino acids and carbohydrates) be formed in the interstellar medium? How do simple molecules evolve into complex biopolymers (e.g. proteins, RNA and DNA) and to which extent is this development affected by influences from space? Which molecular components of cells were formed first: enzymes, genes or membranes? What can lifeforms in extreme environments tell us about life in early stages of our planet (and possibly other planets)?

Degree Programs Astrobiology Overview Graduate Program Overview C319 Physics-Astronomy Building Astrobiology the study of life in the universe investigates the wide range of multidisciplinary factors that may influence the origin and evolution of life on Earth and beyond. Such investigation demands intense interdisciplinarity, for which the astrobiology program at the University of Washington is creating a new community of scholars, investigators, and educators - a community skilled in multidisciplinary methods and thinking that pushes boundaries beyond the commonplace with intellectual vigor, creativity, and rigorous methodology. Astrobiology at the University of Washington builds on the strengths of traditional academic structure to transcend the limits of specialization through the synergy of multidisciplinary cooperation in both research and education. The internationally recognized graduate certificate program offers a rigorous, interdisciplinary curriculum in cooperation with the Ph.D. programs of participating departments. The program's unique features bond students and faculty from widely disparate departments. Participating graduate students gain the personal and professional skills necessary to successfully engage in multidisciplinary collaborations. The emerging field of astrobiology benefits from and is shaped by the perspectives of multiple disciplines directed at a common problem. It benefits also from the breadth of perspective offered by diversity in culture and race among the program's participants.

UA Science Home Contact Background Lake on Saturn’s moon Titan, possibly filled with liquid methane, is larger in size than lake Superior on Earth (right). Link to story: Titan's Lakes. The College of Science established the Center for Astrobiology in 2005 to promote multidisciplinary excellence in research, education and collaboration in the nascent field of astrobiology. The Center for Astrobiology works with researchers, programs, departments and colleges across campus and researchers throughout the world to build the research and educational programs needed to answer the profound questions raised in astrobiology: how did life arise and evolve toward intelligence, is there life elsewhere in the cosmos, and what are the prospects for expansion of Earth life into the cosmos. From an initial core of astronomy, chemistry and planetary researchers funded through NASA’s Astrobiology Institute, the Center is growing to include researchers in the biological sciences, ecology and evolutionary biology, molecular and cellular biology and even hydrology and water resources. Our Mission The College of Science Center for Astrobiology provides interdepartmental, national and international opportunities for collaboration in research and education in the multidisciplinary field of astrobiology. The Center will provide a focal point for interactions between life and physical sciences through joint research, links to international astrobiology efforts, and development of an interdisciplinary astrobiology program at graduate and undergraduate levels. It will provide a nexus for new proposals for federal and private research funding and education and public outreach. It will catapult the University of Arizona into the position of leadership in the training of experts in this rapidly growing field.

Moon to Mars Hot Topic Origins Extreme Life Extreme Animals Extreme Animals Extreme Life Posted: 09/01/02 Author: Leslie Mullen Summary: Because of their ability to withstand hostile conditions, tardigrades and other cryptobiotic organisms are of interest to astrobiologists. Some tardigrades can survive in temperatures as low as minus 200 degrees Celsius (minus 328 F). Image of a tardigrade shot at the American Museum of Natural History in New York in 2001. A Scanning Electro Microscope (SEM) was used to capture the image of the tradigrade. Credit: William R. Miller, Department of Biology, Chestnut Hill College All life on Earth is based on water. The water in our cells constantly needs to be replenished, and if water is not available, we could die. Some organisms, however, have evolved to adapt to a loss of water in essence, to cheat death until water reappears. One such organism is a microscopic animal called a "tardigrade." J.A.E. Goeze, who published the first paper on tardigrades in 1773, said, "Strange is this animal ... because it resembles a bear in miniature." Because of this description, and because tardigrades normally live in water, they are also known as "water bears." Tardigrades look more like a candy Gummy Bear than a grizzly bear they have the bright orange, red or green colors of Gummy Bears, and a gummy surface texture. Their inflated round bodies have four pairs of stubby little legs. They use these clawed limbs to walk, grasping onto lichen or moss as they amble along.
