Preface to “Astrobiology”

Abstract

The outstanding characteristic of Astrobiology is its interdisciplinary approach, which is absolutely essential for raveling our fundamental goals (as set by NASA Astrobiology Program); how life begins and evolves, whether life exists elsewhere in the Universe, and what the future of life on Earth and beyond is. This special issue Astrobiology specifically demonstrates the direction which this study area is going take by putting together remarkable review articles from the perspectives of space exploration, astronomy, geophysics, astrochemistry, abiotic chemistry, isotope geochemistry, and biogeochemistry. All these science are linked each other in terms of the energy balance concept for habitability.
