The Copernican principle, inspired by the mid-16th-century idea of Nicolaus Copernicus that Earth is not the center of the universe, states that we may not be alone in the universe […]
One stated goal of the current generation of Mars rovers is to search for possible ancient biosignatures on Mars. However, the question of what a genuine biosignature would look like […]
The presence of methane (CH4) in the martian atmosphere is of great interest because methane is a potential biosignature. Over the last two decades, trace amounts of methane on Mars […]
The NFoLD and NExSS research coordination networks are hosting a joint virtual workshop on biosignature standards of evidence and reporting protocols from July 19–22, 2021. The workshop will include three […]
The search for signs of life on exoplanets relies heavily on our ability to detect key biosignatures within a given planet’s atmosphere. Among potential markers for life in exoplanet atmospheres, […]
The current episode of the Gravity Assist podcast, hosted by NASA’s Chief Scientist Jim Green, features LPI Staff Scientist Kennda Lynch. Dr. Lynch is an astrobiologist and a geomicrobiologist who studies […]
Jezero crater on Mars is the landing site for the NASA Mars 2020 Perseverance rover, which is due to launch this July. It was selected as the landing site for […]
Biosignature Preservation and Detection First Announcement Now Available! Biosignature Preservation and Detection in Mars Analog Environments #biosignature2016 May 16–19, 2016 Lake Tahoe, Nevada The Biosignature Preservation and Detection in Mars Analog Environments […]
4-16 July 2016 Reykjavik, Iceland This summer school aims to cover the subject of the search for life in different environments, both on early Earth, below Earth’s surface and on […]
Research into biosignature recognition is rapidly evolving, particularly as our understanding of life’s ability to thrive and survive in extreme environments expands. Despite these advances, unambiguous biosignatures are difficult to diagnose. Biosignatures (in the […]
Interpreting in situ enigmatic features (body or trace fossils, isotopic or molecular signatures, chemical disequilibria, or conspicuous mineralization) as indicators of biological activity is a notoriously difficult task. The goal of characterizing biosignatures is […]
BIOSIGNATURES ACROSS SPACE AND TIME Bergen, Norway, 20-22 May 2014 This meeting will to bring together astronomers, geologists, biologists and other interested scientists to share interdisciplinary approaches to detect signs of life […]
