According to scientists, a monster storm rips across Saturn every 30 years or so. Cassini images have allowed scientists to see deeper into the planet’s atmosphere and find that cloud particles at the top of the great 15,000 km wide storm that started back in 2010 are a mix of three substances: water ice, ammonia ice, and a mysterious third substance that might be ammonium hydrosulfide. This is the first time water ice has ever been observed on Saturn. These storms bring what normally lies beneath to the top, driving cloud particles up almost like a volcano, so that they can be seen. They say this find supports that theory that water condensation powers Saturn’s superstorms.
