How and where did life on Earth originate? To date, various environments have been
proposed as plausible sites for the origin of life. However, discussions have focused on a …

The search for evidence of extraterrestrial life in our Solar System is currently guided by our
understanding of terrestrial biology and its associated biosignatures. The observed …

The analysis of amino acids in meteorites dates back over 50 years; however, it is only in
recent years that research has expanded beyond investigations of a narrow set of meteorite …

The nature of organic matter in meteorites reveals information about early solar system
chemistry and the histories of parent bodies as recorded in the effects of physical and …

amino acids in two fragments of the Aguas Zarcas CM 2 type carbonaceous chondrite fall …

Abstract The Asuka (A)‐12236 meteorite has recently been classified as a CM
carbonaceous chondrite of petrologic type 3.0/2.9 and is among the most primitive CM …

Millimeter‐scale rock particles called chondrules are the principal components of the most
common meteorites, chondrites. Hence, chondrules were arguably the most abundant …

Chirality is a central feature in the evolution of biological systems, but the reason for
biology's strong preference for specific chiralities of amino acids, sugars, and other …

Evidence suggests that Saturn's icy moon Enceladus has a subsurface ocean that sources
plumes of water vapor and ice vented to space from its south pole. In situ analyses of this …

Soluble organic compositions of extraterrestrial samples offer valuable insights into the
prebiotic organic chemistry of the solar system. This review provides a summary of the …
