The study of the origin, evolution, distribution, and future of life in the universe (Astrobiology) is one new multidisciplinary field, which encompasses the search for habitable environments in our Solar System and habitable planets outside of it. The search for evidence of prebiotic chemistry, life and research into the origins and early evolution of life on Earth, also studies of the potential for life in space are the other concerns for astrobiologists. In this article first we will have a review on both galactical and stellar life zones also will discuss about exoplanets which are in their stars’ goldilocks, then we will explain the most important Characteristics that are remarkable to find life on a planet. We will also pay attention to some conditions for the situation which we call "Extreme life" on earth that may be the key to find unusual types of life beyond. Finally we will introduce some new methods to detect every possible signs of life (biomarkers) on the atmosphere of a candidate Exoplanet which may be a suitable case for having organic life.
