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.

astrochemistry

[¦as·trō′kem·ə·strē]
(astronomy)
The science that applies the principles of chemistry to matter in space.

Because of this technology, millimeter-wave sensors on satellites have become extremely important tools for gathering data: astrochemistry and continuum noise measurements when the satellite is pointed upward, and weather forecasting (using a variety of measurements), oceanography, ozone and soil moisture measurements when pointed downward.
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.
This was the beginning of what came to be called astrochemistry. Since then, more and more complicated atom groupings have been detected, some involving as many as many as thirteen atoms.
Michael Mautner is a physical chemist and the author of more than 100 articles on ion processes with applications to astrochemistry and biophysics.
[1] A complex organic molecule is defined in astrochemistry as consisting of six or more atoms, where at least one of the atoms is carbon.
Objective: Astrochemistry is an inter-disciplinary field that provides an insight into the complex physical and chemical processes at play during the early evolutionary stages in star-formation.
They cover cosmology and the high redshift universe; galaxies and galactic nuclei; interstellar matrix, star formation, and astrochemistry; circumstellar disks, exoplanets, and the solar system; stellar evolution and the sun; and frontiers of ALMA capabilities.
The emphasis is on problems of inelastic electron scattering in such fields as plasma physics, microelectronics, nanolithography, DNA research, atmospheric chemistry, and astrochemistry. Little attention is devoted to gas-phase elastic electron scattering.
"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. Some of the 20 papers are from an October 2003 conference in Naples.
