Astrobiology
Astrobiology is an area of life science that investigates the origin of life, how the biological components interact to create environment, what makes planets habitable, and searches for life on other planets. Astrobiol-ogists are scientists from many areas of science, including biologists (molecular biologists, microbiologists, ecologists, geneticists), chemists, oceanographers, cli-matologists, archeologists, paleontologists, geologists and astronomers. The foundations of astrobiology were laid in 1920s by a Russian scientist A.I. Oparin, and with his theory of development of organic matter from inorganic components under the conditions resembling early Earth's atmosphere. It took, however, over half a century before studies into evolution of life on Earth and extraterrestial life became an independent branch of life science. Astrobiology was created thanks to NASA's administrator Dan Goldin in The mid-1990s. Coordination of the global effort in astrobiology rests now with the NASA Astrobiology Institute (NAI), created in 1998 and based at Ames in California, and includes over 700 scientists from numerous research institutes in the U.S. affiliate organizations were also created in Europe and Australia.
Aims of astrobiology
The NAI identified three main goals of astrobiology. Primary among these goals is the investigation of the evolution of life principally on Earth. This is achieved by understanding how organic matter became organized into living organisms, and how life and environment co-evolved with Earth. NAI's second aim is to find extrater-restial life by identifying habitable planets. This will require identification of conditions essential for life to develop, and searching for life signatures on planets of the solar system and beyond. The third goal is to determine the future of life on Earth and in outer space. This area is addressed by studying the response of terrestrial organisms to reduced gravity conditions, and investigating how the environmental changes affect life on Earth.
Current research in astrobiology
Studying the Earth history revealed that life appeared on our planet after its surface had adequately cooled down, around 3.8 billion years ago. Fossil evidence indicated that the first organisms were unicellular (one-celled) and anaerobic (non-oxygen requiring). By studying extreme environments such as thermal vents, the freezing waters of the Antarctic, and anoxic marine sediments, scientists are able to determine mechanisms of microbial evolution, and reconstruct the early history of life on Earth.
