A new method for exploring alien life

It's been nearly four decades since Carl Sagan first addressed the general public from a scientist's perspective, confronting the possibility of extraterrestrial life [۱]. Different scientific hypothesis are proposed to answer this controversial question. The search for extrasolar terrestrial planets is in large part motivated by the hope of finding signs of life or habitability via spectroscopic biosignatures [۲]. The main focus of these spectroscopic methods is the direct detection of extrasolar terrestrial planets. However, in some cases searching for spectroscopic signatures by a direct technique (i.e., a direct interaction of radiation and matter) is an impossible goal due to blind spots in the space. In this study, a new approach, based on indirect spectroscopy, for finding out extraterrestrial life on other planets is proposed and compared with another direct spectroscopy.
