Cassini has been snapping visible-light photographs of Saturn's rings, the Composite Infra-red Spectrometer instrument was taking the rings' temperatures. During equinox, the rings cooled to the lowest temperature ever recorded. The A ring dropped down to a frosty 43 Kelvin. Studying ring temperatures at equinox will help scientists better understand the sizes and other characteristics of the ring particles.
