The interstellar medium is characterized by a rich and diverse chemistry. Many of its
complex organic molecules are proposed to form through radical chemistry in icy grain …

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 …

Context. Gas-phase complex organic molecules are commonly detected in the warm inner
regions of protostellar envelopes, so-called hot cores. Recent models show that …

In the past few years, several major space missions have been completed (eg, Deep Impact,
LCROSS, Chandrayaan-1, Stardust, Hayabusa), and a number of spacecraft are currently …

Ceres hosts notable aliphatic-organic concentrations, ranging from approximately 5 to> 30
weight% in specific surface areas. The origins and persistence of these organics are under …

Pure methane ices (CH 4) were irradiated at 10 K with energetic electrons to mimic the
energy transfer processes that occur in the track of the trajectories of MeV cosmic-ray …

Pure ices of amorphous methanol, CH 3 OH (X 1 A'), were irradiated at 11 K by 5 keV
electrons at 100 nA for 1 hr. These energetic electrons simulate electronic energy transfer …

Motivated by detections of nitriles in Titan's atmosphere, cometary comae, and the
interstellar medium, we report laboratory investigations of the low-temperature chemistry of …

Infrared spectra and radiation chemical behavior of N2-dominated ices relevant to the
surfaces of Triton and Pluto are presented. This is the first systematic IR study of proton …

Water ice is a ubiquitous material in space, on the surface of planets and their moons, in
comets and interstellar dust grains. The structure of water ice strongly depends on the …
