Astrochemistry is the study of the abundance and reactions of molecules in the universe, and their interaction with radiation. [1] The discipline is an overlap of astronomy and chemistry . The word "astrochemistry" may be applied to both the Solar System and the interstellar medium .
The discipline of astrochemistry includes understanding how these molecules form and explaining their abundances. The extremely low density of the interstellar medium is not conducive to the formation of molecules, making conventional gas-phase reactions between neutral species (atoms or molecules) inefficient.
Professor Williams field of study is astrochemistry, involving the study of molecular line emissions in outer space to analyse and interpret the evolutionary process of the universe. He led research groups at both Manchester and London and produced more than 300 publications in journals and books.
On April 9, 2015, the Öberg Astrochemistry Group published a paper stating they detected the first complex carbon molecule in a protoplanetary disk, this molecule being methyl cyanide. [ 2 ] [ 5 ] Methyl cyanide (CH 3 CN) is thought to be important for the origins of life because it contains carbon-nitrogen bonds , which make up amino acids ...
Within a few million years the light from bright stars will have boiled away this molecular cloud of gas and dust. The cloud has broken off from the Carina Nebula.Newly formed stars are visible nearby, their images reddened by blue light being preferentially scattered by the pervasive dust.
Porous chondrite dust particle. Cosmic dust – also called extraterrestrial dust, space dust, or star dust – is dust that occurs in outer space or has fallen onto Earth. [1] [2] Most cosmic dust particles measure between a few molecules and 0.1 mm (100 μm), such as micrometeoroids (<30 μm) and meteoroids (>30 μm). [3]
Meteorites are often studied as part of cosmochemistry. Cosmochemistry (from Ancient Greek κόσμος (kósmos) 'universe' and χημεία (khēmeía) 'chemistry') or chemical cosmology is the study of the chemical composition of matter in the universe and the processes that led to those compositions. [1]
In the BitTorrent file distribution system, a torrent file or meta-info file is a computer file that contains metadata about files and folders to be distributed, and usually also a list of the network locations of trackers, which are computers that help participants in the system find each other and form efficient distribution groups called swarms.
