NASA team finds noxious ice cloud on Saturn's moon Titan
Greenbelt MD (SPX) Oct 19, 2017
Researchers with NASA's Cassini mission found evidence of a toxic hybrid ice in a wispy cloud high above the south pole of Saturn's largest moon, Titan. The finding is a new demonstration of the complex chemistry occurring in Titan's atmosphere - in this case, cloud formation in the giant moon's stratosphere - and part of a collection of processes that ultimately helps deliver a smorgasbord of organic molecules to Titan's surface. Invisible to the human eye, the cloud was detected at infrare ... read more

Saturn's A ring contained by not one, but seven moons
Until recently, astronomers assumed Saturn's A ring was contained by a single moon, Janus, the gas giant's largest. But new research shows the A ring, the outermost of Saturn's large, bright rings, is confined by seven moons. ... more
