The satellite of Saturn Titan is very similar to Earth – there is an active cycle of the atmosphere, there are rivers, lakes and seas, the winds change the position of the dunes and destroy the craters. degrees, and methane and ethane are inundated with water. However, life in such an environment might also have existed.
A research is underway that suggests that it is best to look at the traces of Titan's life in craters and cryovolcans, from which liquid water rises. In particular, the lack of liquid water does not allow Titan to form complex compounds necessary for terrestrial life, because the other ingredient – carbon-based organic molecules – is buried there
where liquid water is present, complex chemical reactions can begin. sediment It is impossible to detect them remotely, therefore, to test the hypothesis, a surface probe should be sent to Titan, which would accurately deposit the chemical composition of one of the craters in the Existing water plan and sediments badyzed. Such an badysis would help to determine the evolution of prebiotic processes (that is, before the onset of life) and to answer the question of how life appeared on Earth.
The results of the study are published in Astrobiology. s)
