Original Abstract

The chemical processes initiated by electrical discharges in prebiotic atmospheres became a hot topic during the last decade because of extensive discovering of exo-planets. The biggest atmospheric data collection is about Saturn’s moon Titan atmosphere that is composed mainly from nitrogen and methane at low temperature of about 94 K and pressure about 1.5 atmospheres. The presented contribution gives the first measurement of the main compounds formed in glow discharge in nitrogen-methane gaseous mixture at the liquid nitrogen temperature at pressure of 1.5 atmospheres. The obtained results confirmed formation of many molecules identified at Titan by Huygens landing module. Moreover, the very complex chemistry leading to the formation of currently considered direct life precursors like formamide in significant amount was discovered.
