The Astrobiological Perspective

Abstract

Extraterrestrial life, its beginnings, and its evolution are the subject of astrobiology.1 Some scientists, critical of this new science, expressed doubts about its scientific nature and defined it as the only science that does not have a subject, since there is no evidence that extraterrestrial life actually exists. This is in fact a groundless objection, since astrobiology studies the conditions needed for the development of life and tries to define general laws for evolution from the simplest to the most complex forms of life on the basis of the data that astronomy and astrophysics are slowly accumulating regarding the conditions prevailing on the various celestial bodies.
