Given their thermodynamic stability, the next question becomes: can structures such as these form on relevant timescales on Titan? Our answer is yes. Methane, ethane and HCN can interact over various pressures and temperatures on Titan. In addition to 60 substantial surface deposits, methane and ethane can be found in clouds at altitudes up to 40 km and between 30-65 km, respectively . HCN-rich stratospheric clouds may be much higher, around 140 km and even in the mesosphere . Our 65 experiments rely on temperature cycling (77-170 K) and can therefore be viewed as accelerated model proxies of what may proceed on the surface or in aerosols in the Titan atmosphere.
