The radiation from stars and active galactic nuclei (AGNs) creates photodissociation regions
(PDRs) and X-ray-dominated regions (XDRs), where the chemistry or heating is dominated …

Water is a fundamental molecule in the universe. On Earth, water exists in all three phases:
gas, liquid, and solid (ice). Liquid water facilitates many chemical reactions as a solvent …

The evolution of star-forming regions and their thermal balance are strongly influenced by
their chemical composition, which, in turn, is determined by the physicochemical processes …

The detection of the amino acid glycine and its amine precursor methylamine on the comet
67P/Churyumov-Gerasimenko by the Rosetta mission provides strong evidence for a cosmic …

Since we intend to review experimental and theoretical studies of physicochemical
processes occurring on cosmic dust grains in very cold regions in space, we start with a brief …

Molecular absorption and emission bands dominate the visible, infrared, and submillimeter
spectra of most objects with associated gas. These observations reveal a surprisingly rich …

From the frontiers of research on ice dynamics in its broadest sense, this review surveys the
structures of ice, the patterns or morphologies it may assume, and the physical and chemical …

Context. Near-to mid-infrared observations of molecular emission from protoplanetary disks
show that the inner regions are rich in small organic volatiles (eg, C 2 H 2 and HCN). Trends …

It was in 'The Magellanic Cloud'(1955)–a science fiction novel by Stanislaw Lem–that
engineers travelling to another star noticed that their spacecraft for unknown reasons …

A brief introduction and overview of the astrochemistry of dust, ice and gas and their
interplay is presented. The importance of basic chemical physics studies of critical reactions …
