{{Update Science}}'''Exobiology''' (also called '''astrobiology''' or '''xenobiology''') is the [[biology|biological science]] concerned with living [[alien]] organisms. Exobiology was also a course taught at [[Star Fleet Academy]]. A biologist who specializes in the field of exobiology is referred to as an exobiologist, xenobiologist, or astrobiologist, depending on their specialty. * The '''astrobiology''' specialty is an interdisciplinary scientific field that studies the origins, early evolution, distribution, and future of life in the universe. * This specialty makes use of molecular biology, biophysics, biochemistry, chemistry, astronomy, physical cosmology, exoplanetology, geology, paleontology, <br>and ichnology to investigate the possibility of life on other worlds and help recognize biospheres that might be different from that on Earth and other known [[Category:Class M|M-class]] planets. **The origin and early evolution of life is an inseparable part of the discipline of astrobiology. * '''Xenobiology''' compares various elements of different species. * The sub-discipline known as "comparative xenobiology" is the scientific study of the physiological features of various alien lifeforms. * Difference between '''xeno-, exo-, and astro'''-biology:**"Astro" means "star" and "exo" means "outside". Both exo- and astrobiology deal with the search for naturally evolved life in the Universe, mostly on other planets in the circumstellar habitable zone. **Whereas astrobiologists are concerned with the detection and analysis of life elsewhere in the Universe, xenobiology attempts to design forms of life with a different biochemistry or different genetic code than on planet Earth.

A [[biologist]] who specializes in the field of exobiology is referred to as an [[exobiologist]], xenobiologist, or astrobiologist.
The sub-discipline known as '''comparative xenobiology''' is the scientific study of the [[physiology|physiological]] features of various alien lifeforms. (Refer to comparative xenobiological chart.)
On [[Starbase 515]], an exobiology research division was located in room 03-1444.
[[Lieutenant]] [[Jadzia Dax]] had a [[Premier Distinction]] in exobiology.
A comparative xenobiological chart was placed in [[Keiko O'Brien]]'s [[school]]room aboard [[Deep Space 9]] in [[2369]].
