Life is based on elements that have their origins within the centers of stars. Then organic molecules are formed in the interstellar medium. They can make part of planets some of them appropriate for the origin and prosperity of life. Extrasolar planets are currently discovered and observed by astronomers and are abundant, but extraterrestrial life or at least complex life seems to be scarce

Palabras clave : lifeLife; extraterrestrial life; exoplanets.
