Astrobiology is a new science that arises from the need to investigate the origin, presence and influence of life in the universe. It is a relatively new branch of knowledge, as its starting point can be placed in 1998, when NASA established the NASA Astrobiology Institute (NAI).
Astrobiology is, from its very origin, transdisciplinary. Related sciences such as astronomy, astrophysics, biology, chemistry, geology, computer science, anthropology and philosophy, among others. The essence of astrobiology study is the analysis of scientific problems from the point of view of several independent disciplines with their own methods and approaches. This is especially useful in the case of historical phenomena such as life, in the underlying simple bases such as physics and chemistry that manifest themselves as complex as biology.
There is no agreed definition of astrobiology, although their field of interest is perfectly recognizable in addition to everything that has to do with understanding the phenomenon of life as we know it (its emergence, development conditions, adaptability, extremofilia- , etc.), also involves the search for life beyond Earth (exobiology) and its derivatives, such as space exploration or planetology.
Some of the issues that astrobiology seeks to answer are:
What is life?
How to evolve and develop?
Is there life elsewhere in the universe?
