Extraterrestrial Phenomena

measurement of the Saturnine atmosphere,242 hydrocarbon abundances on Jupiter,243 and the photochemistry of hydrocarbons in the atmosphere of Titan 344 have been discussed. [Pg.135]

The absence of atomic hydrogen in the Lunar atmosphere has been demonstrated with a u.v.-emission probe.280 [Pg.135]


Theoretical chemistry involves explaining chemical phenomenon using natural laws. The primary tool of theoretical chemistry is quantum chemistry, and the field may be divided into electronic structure calculations, reaction dynamics and statistical mechanics. These three play a role in addressing an issue of primary concern understanding photochemical reaction rates at the various conditions found in the atmosphere. Atmospheric science includes both atmospheric chemistry and atmospheric physics, meteorology, climatology and the study of extraterrestrial atmospheres. [Pg.4]

This demonstrates that those amino acids present in the Murchison meteorite, which also play the role of protein monomers, are indeed of extraterrestrial origin. In addition, chemical analysis has demonstrated the presence of a variety of amino acids in the Ivuna and Orgueil meteorites (Ehrenfreund et al., 2001). If the presence of biomolecules on the early earth is due in part to the bombardment of interplanetary dust particles, comets, and meteorites, then the same phenomenon could be taking place in any other solar system. [Pg.156]

The observations of extraterrestrial neutrinos from the sun by different experimental methods have confirmed the details of the nuclear processes in the core of the sun and have verified its internal structure and method of energy generation. Moreover, the neutrinos from the earth s atmosphere and from the sun appear to exhibit the phenomenon of neutrino oscillations which, if fully verified, will conclusively demonstrate that at least one of the neutrinos in the current model of elementary leptons has nonzero mass and that at least two of them can spontaneously exchange flavor. [Pg.209]
