New clues about how Titan’s haze was formed - space science news

In a multidisciplinary approach including laboratory experiments, computer simulations and modeling, scientists found that the complex carbon structures found in the atmosphere of Saturn’s moon Titan could have been formed through chemical reactions under low temperature. This is contrary to current views that assume that the complex carbon structures, polycyclic aromatic hydrocarbons (PAHs), require high temperatures. The laboratory experiments formed the chemicals that have been observed in the atmosphere of Titan, the precise reaction mechanisms were revealed by the computer simulations, and the modeling showed how gases should flow so that they mix properly to produce the PAHs that form the brownish haze in Titan’s atmosphere.
