Researchers report that Saturn's moon Enceladus is covered in superfine powdery snow. From National Geographic:
"The particles are only a fraction of a millimeter in size … even finer than talcum powder," study leader Paul Schenk, a planetary scientist at the Lunar and Planetary Institute in Houston, Texas, said in a statement. "This would make for the finest powder a skier could hope for.""Pictures: Saturn Moon Coated in Fresh Powder" Discuss Next post
The finding is based on new high-resolution pictures of Enceladus from NASA's Cassini orbiter, as well as global maps of color patterns that help reveal the ages of surface features.
