There have been some interesting findings from a research team led by the University of Arizona, indicating that amino acids and other complex building blocks of life may be present in Titan’s atmosphere, and that the processes involved can occur in the upper atmosphere of a planet or moon, without the need for liquid water as has long been presumed.
Simulations of Titan’s atmosphere, subjected to UV radiation (like from the sun, as happens in the upper Titanian atmosphere) produced complex organic molecules such as amino acids and nucleotide bases, the primary building blocks of life on Earth. The Cassini spacecraft has already confirmed organic molecules there, but there are some more complex ones in the atmosphere which haven’t been identified yet.
As has been reported previously, there has has been a growing interest lately in the possibility of primitive life on Titan, despite the very cold temperatures, given the hydrological cycle of rain, rivers, lakes and seas, but with liquid methane instead of water. If prebiological molecules are being massively produced, as seems to be the case, could anything be alive in those alien lakes and seas…?
