Gas-phase prebiotic chemistry in extraterrestrial environments [PDF]

open access: bronzeProceedings of the International Astronomical Union, 2009
AbstractA variety of molecular species up to complex polyatomic molecules/radicals have been identified in many extraterrestrial gaseous environments, including interstellar clouds, cometary comae and planetary atmospheres. Amongst the identified molecules/radicals, a large percentage are organic in nature and encompass also prebiotic molecules ...
