Zoé Magazine Number 3

The & nbsp; leitmotiv & nbsp; of our Astrobiology Center is to understand how life originated and how it evolved , starting from the boundary conditions given by the evolution of the Universe from the Big Bang to the formation of the Solar System, and from our knowledge of the environment on Earth in the last 3000 million years. < p class = "p1" style = "text-align: justify;"> The advances in Astrophysics of recent decades have shown us how the evolutionary line of the Universe naturally generates a large number of planets around an important fraction of the stars that are in the Universe. To date we have confirmed more than 1000 of these exoplanets; In fact we are witnessing the birth of a new science: exoplanetology. But as expected, the environmental conditions in most of these new worlds differ markedly from those we have on Earth.

Exoplanetologists have defined what they call the & nbsp; Habitability Zone & nbsp; of a star like those orbits where a rocky planet could be at the right temperature to hold liquid water and gaseous atmospheres. But even exoplanets that are in this Habitability Zone will necessarily show great variations in their physicochemical properties.

The question that arises from Immediate way is: Could life develop in environments very different from terrestrial ones? In order to answer this question, it began many years ago with the search for living beings in extreme environments, in which a priori nothing should have survived. The surprise was to find that even in the most extreme environments life had adapted and evolved.

In this issue of Zoé magazine we will review the major advances in this field of the extremity , which shows us the ability to adapt biological processes once they are launched. What these results have made clear to us is that if life also arose outside the Earth, it should be a very frequent phenomenon that we found in very diverse environments. We just have to look for it, and that's what we are in.
