Astrobiology, in the past known as exobiology, is an interdisciplinary logical field worried about the starting points, early development, conveyance, and eventual fate of life known to mankind. Astrobiology considers the subject of whether extraterrestrial life exists, and on the off chance that it does, how people can recognize it. Astrobiology utilizes atomic science, biophysics, natural chemistry, science, space science, physical cosmology, exoplanetology and geography to research the chance of life on different universes and help perceive biospheres that may be not quite the same as that on Earth. The source and early advancement of life is an indistinguishable piece of the control of astrobiology. Astrobiology frets about understanding of existing logical information, and in spite of the fact that hypothesis is engaged to give setting, astrobiology concerns itself basically with speculations that fit immovably into existing logical speculations.
