Despite the generally hostile nature of the environments involved, chemistry does occur in
space. Molecules are seen in environments that span a wide range of physical and chemical …

Clouds of gas and dust in the Galaxy are nurseries in which stars and planetary systems are
born. During their journey from the diffuse interstellar medium to the protoplanetary disks …

Complex organic molecules (COMs) can be produced by energetic processing of interstellar
ice mantles accreted on top of dust grains. Two COMs with proposed energetic ice formation …

Telescope or ground-based observatories like the European Extremely Large Telescope …

For the last century, the source of sulfur in Earth's very first organisms has remained a
fundamental, unsolved enigma. While sulfates and their organic derivatives with sulfur in the …

Abstract The dwarf planets Sedna, Gonggong, and Quaoar are interesting in being
somewhat smaller than the methane-rich bodies of the Kuiper Belt (Pluto, Eris, Makemake) …

In astrochemistry, complex organic molecules (COMs) are defined as species with at least
one C atom and six or more atoms in total. More than 70 COMs were detected toward …

Titan has a diverse range of materials in its atmosphere and on its surface: the simple
organics that reside in various phases (gas, liquid, and ice) and the solid complex refractory …

Dangling bond (DB) bands in IR spectra, above 3600 cm− 1, are a source of information on
structural properties of amorphous water ice, and especially on ice mixtures of water and …

We report the density and refractive index, at 633 nm, of ethane and ethylene ices at
temperatures from 13 to 65 K, measured by double laser interferometry and a cryogenic …
