The astronomy is the discipline science that focuses on the study of the universe: its origin and evolution , as well as the constellations and galaxies that comprise it . The biology studies everything related to life, ie the set of processes that explain any phenomena associated with life in all its forms. Both sciences have been merged into another area of knowledge, astrobiology.
The main research object
Astrobiologists try to give an answer to one of the enigmas of humanity: are we alone in the universe? Life on our planet takes on all kinds of forms and expressions, but it is unknown whether other different forms of life exist in other parts of the universe.
In the field of astrobiology, experts are faced with all kinds of questions. It makes sense to think that on distant planets life appears in the form of microbes, hybrid organisms that combine the biological with the electronic, or directly extraterrestrial beings.
The study of extraterrestrial life depends largely on the knowledge of life on our planet
In the search for extraterrestrial life there is a previous question that still does not have a definitive explanation: how did life arise on Earth? If there is a definitive answer one day, there will be more information about life elsewhere in the universe.
The position of the Earth with respect to the Sun, the temperature levels and the presence of oxygen to be able to breathe are the essential conditions that allow the development of any type of life, from unicellular organisms to large mammals.
Finding water in a liquid state in a star would be an indication for astrobiology students
Astrobiologists believe that anywhere there is water, it is possible to think that some form of life is found there. This finding has already occurred (for example, in some comets, on Mars or on the moons of Saturn) but the water found appears in the form of ice and this circumstance reduces the probability of finding life in any of its forms.
On the other hand, the study of geological erosion on other planets is another area that astrobiologists investigate in the search for life beyond our planet.
Astrobiology is a relatively recent discipline, having emerged in the middle of the 20th century. The answers that a future can provide will be decisive for humanity to consider living on other planets.
