It is not to be confused with Xenobiology. Astrobiology is the study of the origin, evolution, distribution, and future of life in the universe extraterrestrial life and life on Earth. Astrobiology addresses the question of whether life exists beyond Earth, and how humans can detect it if it does. The term exobiology is similar but more specificit covers the search for life beyond Earth, and the effects of extraterrestrial environments on living things. Astrobiology makes use of physics, chemistry, astronomy, biology, molecular biology, ecology, planetary science, geography, and geology to investigate the possibility of life on other worlds and help recognize biospheres that might be different from that on Earth. The origin and early evolution of life is an inseparable part of the discipline of astrobiology. Astrobiology concerns itself with interpretation of existing scientific data, and although speculation is entertained to give context, astrobiology concerns itself primarily with hypotheses that fit firmly into existing scientific theories. Given more detailed and reliable data from other parts of the universe, the roots of astrobiology itselfphysics, chemistry and biologymay have their theoretical bases challenged.

According to the panspermia hypothesis, microscopic lifedistributed by meteoroids, asteroids and other small Solar System bodiesmay exist throughout the universe. According to research published in August 2. Milky Way. 1. 3 Nonetheless, Earth is the only place in the universe humans know to harbor life. Estimates of habitable zones around other stars,1. Goldilocks zones, along with the discovery of hundreds of extrasolar planets and new insights into extreme habitats here on Earth, suggest that there may be many more habitable places in the universe than considered possible until very recently. Current studies on the planet Mars by the Curiosity and Opportunityrovers are searching for evidence of ancient life as well as plains related to ancient rivers or lakes that may have been habitable. The search for evidence of habitability, taphonomy related to fossils, and organic molecules on the planet Mars is now a primary NASA and ESA objective. OvervieweditThe term was first proposed by the Russian Soviet astronomer Gavriil Tikhov in 1. Astrobiology is etymologically derived from the Greek, astron, constellation, star, bios, life and, logia, study. The synonyms of astrobiology are diverse however, the synonyms were structured in relation to the most important sciences implied in its development astronomy and biology. A close synonym is exobiology from the Greek, external, bios, life and, logia, study. The term exobiology was coined by molecular biologist Joshua Lederberg. Exobiology is considered to have a narrow scope limited to search of life external to Earth, whereas subject area of astrobiology is wider and investigates the link between life and the universe, which includes the search for extraterrestrial life, but also includes the study of life on Earth, its origin, evolution and limits. It is not known whether life elsewhere in the universe would utilize cell structures like those found on Earth. Chloroplasts within plant cells shown here. Another term used in the past is xenobiology, biology of the foreigners a word used in 1. Robert Heinlein in his work The Star Beast. The term xenobiology is now used in a more specialized sense, to mean biology based on foreign chemistry, whether of extraterrestrial or terrestrial possibly synthetic origin. Since alternate chemistry analogs to some life processes have been created in the laboratory, xenobiology is now considered as an extant subject. While it is an emerging and developing field, the question of whether life exists elsewhere in the universe is a verifiable hypothesis and thus a valid line of scientific inquiry. Though once considered outside the mainstream of scientific inquiry, astrobiology has become a formalized field of study. Planetary scientist David Grinspoon calls astrobiology a field of natural philosophy, grounding speculation on the unknown, in known scientific theory. NASAs interest in exobiology first began with the development of the U. S. Space Program. In 1. 95. 9, NASA funded its first exobiology project, and in 1. NASA founded an Exobiology Program, which is now one of four main elements of NASAs current Astrobiology Program. In 1. 97. 1, NASA funded the search for extraterrestrial intelligence SETI to search radio frequencies of the electromagnetic spectrum for interstellar communications transmitted by extraterrestrial life outside the Solar System. NASAs Viking missions to Mars, launched in 1. Mars. In June 2. 01. John W. Kluge Center of the Library of Congress held a seminar focusing on astrobiology. Panel members L to R Robin Lovin, Derek Malone France, and Steven J. Dick. Advancements in the fields of astrobiology, observational astronomy and discovery of large varieties of extremophiles with extraordinary capability to thrive in the harshest environments on Earth, have led to speculation that life may possibly be thriving on many of the extraterrestrial bodies in the universe. A particular focus of current astrobiology research is the search for life on Mars due to this planets proximity to Earth and geological history. There is a growing body of evidence to suggest that Mars has previously had a considerable amount of water on its surface, water being considered an essential precursor to the development of carbon based life.

Missions specifically designed to search for current life on Mars were the Viking program and Beagle 2 probes. The Viking results were inconclusive,3. Beagle 2 failed minutes after landing. A future mission with a strong astrobiology role would have been the Jupiter Icy Moons Orbiter, designed to study the frozen moons of Jupitersome of which may have liquid waterhad it not been cancelled. In late 2. 00. 8, the Phoenix lander probed the environment for past and present planetary habitability of microbiallife on Mars, and researched the history of water there. In November 2. 01. NASA launched the Mars Science Laboratory mission carrying the Curiosity rover, which landed on Mars at Gale Crater in August 2. The Curiosity rover is currently probing the environment for past and present planetary habitability of microbiallife on Mars. On 9 December 2. 01. NASA reported that, based on evidence from Curiosity studying Aeolis Palus, Gale Crater contained an ancient freshwater lake which could have been a hospitable environment for microbial life. The European Space Agency is currently collaborating with the Russian Federal Space Agency Roscosmos and developing the Exo. Mars astrobiology rover, which is to be launched in 2. Meanwhile, NASA is developing the Mars 2.
