520 _a"Will we recognize alien life if we stumble across it? Maybe not. It's highly unlikely, after all, that the cameras of our space probes will capture images of planetary surfaces covered with organisms, or the artifacts of intelligent life-forms. Chances are the evidence will be much more subtle: tantalizing spectral lines of biomolecules in the light from a distant earthlike world, or structures within rocks from another planet that are not of obvious geological (or even biological) origin." (ASTRONOMY) This article explains what is necessary for life and examines the possibility of alien life being present in the universe.
