Astrobiologists Take Interdisciplinary Approach To Biosignatures SpaceDaily

A team of interdisciplinary astrobiologists from NASA and other agencies is homing in on recognizing the microbial biosignatures for life, making it easier someday to identify life on other planets. A scientific paper analyzing the team’s research results, titled “Modern Freshwater Microbialite Analogues for Ancient Dendritic Reef Structures,” will be published in the magazine Nature on Oct. 5. The paper focuses on the study of mounded microbialite deposits – layers of living and non-living organisms – found at Pavilion Lake in Canada. Microbialites are organic sedimentary mineral deposits covered by a thin layer of microbes that become entombed in the mounds as they grow outward.
