Story summary

The National Aeronautics and Space Administration (NASA) and Chalmers University report hydrogen cyanide forms stable co-crystals with methane and ethane on Titan, challenging the "like dissolves like" rule.
This finding upends long-held assumptions about molecular interactions in frigid, low-temperature environments.
Scientists also speculate Titan could host a tiny biosphere, with microbial life fermenting organics, totaling a few kilograms.
The results shift views of chemistry and biology beyond Earth.
