The emergence of a new field in science - Exobiology

Exobiology, also known as Astrobiology, refers to the study of the conditions necessary to support the independent development of extraterrestrial life. Direct proof has not yet been found of life anywhere in the universe other than on the Earth, but scientifically sound arguments have been proposed in support of such a possibility. The findings of modern astronomy suggest that a large number of stars could have planets orbiting them that provide conditions suitable for life, …

…bodies. Scientists considers the paleo-emergence of life on Earth and Mars and the relevance of microbial extremophiles from the deep subsurface and hydrothermal vents and ancient viable microorganisms from deep ice in the polar caps and permafrost to planetary habitats and Astrobiology. Morphological, biogeochemical and stable isotope biomarkers and methodologies important for the recognition of bio-genicity in ancient terrestrial rocks, meteorites, astromaterials and samples from space missions to other solar system bodies will be developed.
