ASTROPHYSICAL SOURCES OF RADIATION AND LIFE IN THE UNIVERSE

ABREVAYA, X.C.

Conferencia; MWN conference; 2023

Astrobiology explores the possibility to find life outside the Earth in other planetary bodies, but which are the fundamental factors that can be beneficial or detrimental to the existence of life on other planets? Radiation plays a fundamental role in it, therefore is essential to study its impact at different scales in the universe to unravel which regions of the universe, and ultimately which planets, could host life. Additionally, it is essential to note that, based on “life as we know it”, microorganisms are considered par excellence models of “life” in astrobiological-related research, given that this biological search is mainly oriented towards the finding of simple life forms. In this talk, I will make a brief review of the current knowledge we have on the topic of the influence of the astrophysical sources of radiation on life (e.g.: stellar radiation), and I am going to focus on some particular cases of microbiological experiments under laboratory conditions used to simulate radiation environments to obtain some answers in reference of the effects of stellar radiation at planetary scales.
