Chiral molecule discovered in space A chiral molecule is one that has two forms that are mirror images of each other: enantiomers. Biological systems overwhelmingly use one enantiomer over another, and some meteorites show an excess of one type. The two forms are almost identical chemically, so how this excess first arose is unknown. McGuire et al. used radio astronomy to detect the first known chiral molecule in space: propylene oxide. The work raises the prospect of measuring the enantiomer… 

The quest of chirality in the interstellar medium

Context. All but one complex organic molecule (COM) detected so far in the interstellar medium (ISM) are achiral; propylene oxide (c-C2H3O)-CH3 is the only exception to this. Finding other chiral

Possible chemical and physical scenarios towards biological homochirality.

TLDR
Several scenarios will be discussed that are aimed to reflect the different debates about the emergence of BH: extra-terrestrial or terrestrial origin, nature of the mechanisms leading to the propagation and enhancement of the primeval chiral bias, and temporal sequence between chemical homochirality, BH and life emergence.

TLDR
It is argued that each of these mechanisms leads to different observational consequences for the existence of enantiomeric excesses in the authors' solar system and in exoplanets, pointing to the possibility that the search for life elsewhere will help elucidate the origins of homochirality on Earth.

The Astrochemical Observatory: Experimental and Computational Focus on the Chiral Molecule Propylene Oxide as a Case Study

TLDR
A survey of recent advances in chiral research is presented, designing and illustrating a number of possible experiments for the demonstration of chiral effects in the dynamics of the intermolecular interactions, suggesting a scenario for a stereo-directional origin of chirality.

TLDR
The present review summarizes recent theoretical and experimental efforts to discriminate enantiomers via NMR spectroscopy, with the focus on the deep connection between chirality and symmetry properties under the combined set of fundamental discrete operations, namely charge conjugation, parity (space inversion) and time (motion) reversal.

Laboratory Investigations into the Spectra and Origin of Propylene Oxide: A Chiral Interstellar Molecule

Propylene oxide was recently identified in the interstellar medium, but few laboratory results are available for this molecule to guide current and future investigations. To address this situation,

Emergence of homochirality in large molecular systems

TLDR
It is shown that large molecular systems are likely to undergo a phase transition toward a homochiral state, as a consequence of the fact that they contain a large number of chiral species.

Chirality in molecular collision dynamics

TLDR
Ideas and recent advances about the role of chirality in molecular collisions are reviewed, designing and illustrating molecular beam experiments for the demonstration of chiral effects and suggesting a scenario for a stereo-directional origin of Chiral selection.

Isotopic evidence for extraterrestrial non- racemic amino acids in the Murchison meteorite

TLDR
It is shown that individual amino-acid enantiomers from Murchison are enriched in 15N relative to their terrestrial counterparts, so confirming an extraterrestrial source for an L-enantiomer excess in the Solar System that may predate the origin of life on the Earth.
