Cryovolcanic Geysers

The vapor plumes observed on … are caused by intense cryovolcanic activity deep within the lower mantle, expelling vast columns of nitrogen and ammonia gas upwards. The plumes rise vertically until they reach the limits of the planet's atmosphere, where solar winds cause them to abruptly flatten off. By studying the small variations in the chemical contents of these unique fume formations we can learn more about the complex geological processes of the planet's core.
