A quadruple transit of the moons of Saturn captured by Hubble Space Telescope

Today's featured list: The moons of Saturn are numerous and diverse, ranging from tiny moonlets less than 1 kilometer (0.62 mi) across to the enormous Titan, which is larger than the planet Mercury. Saturn has sixty-two moons with confirmed orbits, fifty-three of which have names, and only thirteen of which have diameters larger than 50 kilometers (31 mi). Saturn has seven moons that are large enough to become spherical, and dense rings with complex orbital motions of their own.

Today's featured topic: The Guadalcanal Campaign was fought between August 1942 and February 1943 on and around the island of Guadalcanal in the Pacific theatre of World War II. Allied forces, predominantly American, landed on the islands of Guadalcanal, Tulagi, and Florida in the southern Solomon Islands, overwhelming the Japanese defenders and capturing an airfield (later named Henderson Field). The Japanese made several attempts to retake Henderson Field. Three major land battles, five large naval battles, and continual, almost daily aerial battles culminated in the decisive Naval Battle of Guadalcanal in early November 1942. The Guadalcanal campaign was a significant strategic combined arms victory by Allied forces over the Japanese in the Pacific theatre.
