The exobiology is a discipline that is dedicated to examine the possibility of life outside the planet Land. It is a field of knowledge that combines contributions from the chemistry, the physical, the astronomy and other sciences.
Investigate the birth and development of the planetary system, study organic compounds in the space and analyzing the habitability conditions of other planets are part of the tasks carried out by experts in exobiology. It is important to bear in mind that these specialists start from scientific data and they work with hypotheses that conform to already accepted theories.
So far, human knowledge recognizes a only place that harbors life: the planet Earth. However, it is believed that there may be life in other corners of the galaxy and even on planets that are not part of the solar system.
Exobiology is often associated with astrobiology and even both terms are used synonymously. Despite this, astrobiology is dedicated to life throughout the world. universe, both in the Land as in outer space, while exobiology is limited to what happens beyond the confines of Earth.
As the Land is the only known place alive, usually exobiology appeals to simulations and makes forecasts based on the fundamental laws of the biology, the chemistry and the physical. So you can generate hypotheses and predictions. Given the lack of samples of extraterrestrial life, it usually resorts to terrestrial microorganisms that live in extreme conditions to carry out its projections.
