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. Given the influx of new information about planetary systems around other stars, its mandate has expanded beyond the study of exobiology (from Greek: έξω, exo , "outside") per se. The term "Xenobiology" is sometimes used as well. Some major astrobiological research topics include: What is life ? How did life arise on Earth ? What do astrophysical observations tell us about the present and future of life 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?

EDUCATION Astrobiology CONFERENCES MEMBERS NEWS OUTREACH Two Columns General Information About the GCA A modified HST image of NGC 3603 showing the life cycle of material (including carbon) in a star-forming region.. 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?

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."

Historical Background Scientific Objectives Staff ... NEW THEORY OF THE ORIGIN OF LIFE Wecome to the Cardiff Centre for Astrobiology (CCAB) website. Astrobiology has emerged as a new science for the new millennium. It seeks to understand life in the context of the wider cosmos. The new Centre will continue in the pioneering traditions of astrobiology started in Cardiff over 25 years ago, taking note of the many relevant discoveries that have been made in recent years. The Centre aims to combine the expertise of astronomers, biochemists and microbiologists to generate cutting edge science that would eventually enable us to answer the age-old question: where did we come from?
