α-Amino acids are easily accessible through abiotic processes and were likely present
before the emergence of life. However, the role they could have played in the process …

Scientists use the Earth as a tool for astrobiology by analyzing planetary field analogues (ie
terrestrial samples and field sites that resemble planetary bodies in our Solar System). In …

Ribose is the central molecular subunit in RNA, but the prebiotic origin of ribose remains
unknown. We observed the formation of substantial quantities of ribose and a diversity of …

Chondrites accreted the oldest solid materials in the solar system including dust processed
in the protoplanetary disk and diverse organic compounds. After accretion, asteroidal …

Comets are known to harbour simple ices and the organic precursors of the building blocks
of proteins—amino acids—that are essential to life. Indeed, glycine, the simplest amino acid …

Evolved interstellar ices observed in dense protostellar molecular clouds may arguably be
considered as part of precometary materials that will later fall on primitive telluric planets …

The discovery of meteoritic amino acids with enantiomeric excesses of the l-form (ee L) has
suggested that extraterrestrial organic materials may have contributed to prebiotic chemistry …

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 …

Circularly polarized light (CPL) is known to be a true chiral entity capable of generating
absolute molecular asymmetry. However, the degree of inducible optical activity depends on …

All life on Earth contains amino acids and carbonaceous chondrite meteorites have been
suggested as their source at the origin of life on Earth. While many meteoritic amino acids …
