astrochemistry

(ass-troh-kem -iss-tree) The study of the chemistry of celestial bodies and of the intervening regions of space. It involves the detection and identification, principally by spectroscopy, of the inorganic and organic chemicals present and the study of the reactions by which these neutral and charged atoms and molecules could have been produced and of future chemical processes. See also molecular-line radio astronomy.

Fully understanding the cosmic chemical landscape will be aided by other fields, including combustion and atmospheric science (which are light-years ahead of astrochemistry in both theory and experiment).
Some even think cometary debris raining down on early Earth "may potentially have played key roles in the origin of life," says researcher Scott Sandford at NASA's Astrochemistry Lab in California.
Professor Kwok's area of research is stellar evolution and astrochemistry.
In TUNNELCHEM, we will investigate aspects of tunneling in several different areas of chemistry: biochemistry, astrochemistry, catalysis and algorithmic development.
The emphasis is on problems of inelastic electron scattering in such fields as plasma physics, microelectronics, nanolithography, DNA research, atmospheric chemistry, and astrochemistry.
Besides astronomical applications, this PAH database and software can be useful as a new research tool for scientists, educators, policy makers, and consultants working in the fields of medicine, health, chemistry, fuel composition, engine design, environmental assessment, environmental monitoring, and environmental protection," said Louis Allamandola, an astrochemistry researcher at NASA's Ames Research Center.
Among the topics are carbon chain molecules in cryogenic matrices, synthesizing carbynoid structures by the combustion flame method, polyyne-type materials, the ion irradiation of solid carbons, and cyanoalkynes and cyanopolyynes from crossed- beam experiments to astrochemistry.
This science of astrochemistry proceeds by examining the spectra of objects in the sky for emissions or absorptions of radiation characteristic of different chemical substances, either fairly sharp wavelengths (lines) or short ranges of wavelengths (bands).
