Titan's atmosphere is also thought to be very similar to what Earth's atmosphere was a long time ago. By learning about Titan, we'll learn about our own planet. NASA ASTROBIOLOGY FIELD SITES AROUND THE WORLD NASA ASTROBIOLOGY ROADMAP 2008 The NASA Astrobiology Roadmap is updated periodically as part of the space agency's strategic planning process. Accordingly, Dr. J. D. Rummel, Senior Scientist for Astrobiology in the Science Mission Directorate at NASA Headquarters, directed that the 2003 version of the Astrobiology Roadmap should be revised and updated during 2007-2008. The ongoing development of the roadmap embodies the contributions of diverse scientists and technologists, including NASA employees, academic scientists whose research is partially funded by NASA grants, and many members of the broader community who have no formal association with NASA. The members of the roadmap revision team are as follows: D. J. Des Marais (co-lead), J. A. Nuth III (co-lead), L. J. Allamandola, A. P. Boss, J. D. Farmer, T. M. Hoehler, B. M. Jakosky, V. S. Meadows, A. Pohorille, B. Runnegar and A. M. Spormann. The team's updated draft was recently reviewed by the Executive Council of the NASA Astrobiology Institute and by the National Academy of Sciences Space Studies Board Committee on the Origins and Evolution of Life.

Astrobiology From Wikipedia, the free encyclopedia Jump to: navigation search This article is about the scientific discipline. For the journal, see Astrobiology (journal) The DNA structure might not be the only nucleic acid in the universe capable of supporting life Astrobiology (from Greek: ἀστρο, astro , "constellation"; βίος, bios , "life"; and λόγος, logos , "knowledge") is the interdisciplinary study of life in the universe, combining aspects of astronomy biology and geology It is focused primarily on the study of the origin , distribution and evolution of life. It is also known as exobiology (from Greek: έξω, exo , "outside"). The term "Xenobiology" has been used as well, but this is technically incorrect because its terminology means "biology of the foreigners". 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 on other planets? Will it be DNA/Carbon based or based on something else? What will it look like?

Exobiology and Astrobiology: the New Science Overview Links Scientists Widen the Hunt for Alien Life (excellent) " ... a quiet revolution is now challenging this view and shaking the foundations of exobiology, the study of the possibility of life elsewhere in the cosmos. Alien life, the new thinking goes, might not actually need the warming rays of a nearby star. It might thrive inside dim moons and planets. The dark ecosystems would be warmed by inner heat, bathed in melted ice and powered by chemicals." New York Times, 5/6/97 The Search for Life on Other Planets (book summary) " In The Search for Life on Other Planets, Jakosky offers a scientific foundation for thinking there may be life elsewhere in the Universe. Using the early history of the Earth and the conditions that would allow life to exist, he creates a sound, scientific foundation for the possibility of life on planets other than our own."

The image to the left represents the research that is performed at the Goddard Center for Astrobiology (GCA). As a part of the NASA Astrobiology Institute (NAI) , the central goal of the Goddard Center for Astrobiology is to understand how organic compounds are created, destroyed, and altered during stellar evolution leading up to the origin of life on a planet, such as Earth. Planetary systems form by collapse of dense interstellar cloud cores. Some stages in this evolution can be directly observed when stellar nurseries are imaged, while other stages remain cloaked behind an impenetrable veil of dust and gas. Yet to understand the origin of life on Earth, we must first develop a comprehensive understanding of the formation of our own planetary system. To understand the probability of finding life elsewhere we must understand both the similarities and differences between the evolution of our own system and that of a typical star. So what exactly is astrobiology? Astrobiology is a multidisciplinary science that involves Astronomy, Biology, Chemistry, Geology, and Physics, all combined to understand the origins of life on Earth and beyond. Scientists who study Astrobiology ask the questions:How did our solar system form? How is the formation of our solar systems similar or different from others? How did the organic molecules we observe in space get to the Earth? What conditions are most suitable for life?

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.
