Indigenous amino acids in primitive CR meteorites
CR chondrites are among the most primitive meteorites. In this paper, we report the first measurements of amino acids in Antarctic CR meteorites. Three CRs, Elephant Moraine (EET) 92042, GravesExpand
Extraterrestrial nucleobases in the Murchison meteorite
Abstract Carbon-rich meteorites, carbonaceous chondrites, contain many biologically relevant organic molecules and delivered prebiotic material to the young Earth. We present compound-specific carbonExpand
Amino acids in Antarctic CM1 meteorites and their relationship to other carbonaceous chondrites
CM2 carbonaceous chondrites are the most primitive material present in the solar system, and some of their subtypes, the CM and CI chondrites, contain up to 2 wt% of organic carbon. The CM2Expand
Earth as a Tool for Astrobiology—A European Perspective
Scientists use the Earth as a tool for astrobiology by analyzing planetary field analogues (i.e. terrestrial samples and field sites that resemble planetary bodies in our Solar System). In addition,Expand
Extraterrestrial Amino Acids
Shock synthesis of amino acids from impacting cometary and icy planet surface analogues
Comets harbour the organic precursors of amino acids. High-velocity impact experiments into icy targets suggest that impacts involving icy planetary bodies could be a viable pathway to synthesize theExpand
The amino acid and hydrocarbon contents of the Paris meteorite: Insights into the most primitive CM chondrite
The Paris meteorite is one of the most primitive carbonaceous chondrites. It is reported to be the least aqueously altered CM chondrite, and to have experienced only weak thermal metamorphism. WeExpand
Amino acid analyses of Antarctic CM2 meteorites using liquid chromatography‐time of flight‐mass spectrometry
Amino acid analyses of the Antarctic CM2 chondrites Allan Hills (ALH) 83100 and Lewis Cliff (LEW) 90500 using liquid chromatography-time of flight-mass spectrometry (LC-ToF-MS) coupled with UVExpand
Astrobiology and the Possibility of Life on Earth and Elsewhere…
Astrobiology is an interdisciplinary scientific field not only focused on the search of extraterrestrial life, but also on deciphering the key environmental parameters that have enabled the emergenceExpand
Organic Chemistry of Carbonaceous Meteorites
The early Solar System contained a wide range of abiotic organic compounds. As the Solar System evolved, these organic molecules were incorporated into planetesimals and eventually planetary bodies,Expand
