A voyage from dark clouds to the early Earth
TL;DR: In this article, it is shown that the same chemical pathways are widespread both in the Milky Way and in external galaxies and that the complexity of organic molecules in different space environments is determined by physical and chemical conditions, including density, temperature, ultraviolet radiation and energetic particle flux.

Ion chemistry and N-containing molecules in Titan's upper atmosphere
TL;DR: In this paper, the Ion and Neutral Mass Spectrometer (INMS) onboard the Cassini spacecraft performed the first composition measurements of Titan's ionosphere and revealed that Titan has the most compositionally complex ionosphere in the Solar System, with roughly 50 ions at or above the detection threshold.

Photochemistry of the atmosphere of Titan: comparison between model and observations.
TL;DR: The photochemistry of simple molecules containing carbon, hydrogen, nitrogen, and oxygen atoms in the atmosphere of Titan has been investigated using updated chemical schemes and the authors' own estimates of a number of key rate coefficients, which satisfactorily accounts for the concentrations of minor species observed by the Voyager IRIS and UVS instruments.

Study of the reactions N+2+2N2→N+4+N2 and O+2+2O2→O+4+O2 from 20 to 160 K by the CRESU technique
TL;DR: In this article, the rate coefficients k1 and k2 for the association reaction N+2+2 N2→k1N+4+N2 and O+ 2+2 O2 →k2O+4 +O2 in the temperature range 20-160 K, using a supersonic jet apparatus (CRESU), were determined.
