Saturn and Six Moons

How many moons does Saturn have? So far 82 have been confirmed, the smallest being only a fraction of a kilometer across. Six of its largest satellites can be seen here in a composite image with 13 short exposure of the bright planet, and 13 long exposures of the brightest of its faint moons, taken over two weeks last month. Larger than Earth’s Moon and even slightly larger than Mercury,Saturn’s largest moon Titan has a diameter of 5,150 kilometers and was captured making nearly a complete orbit around its ringed parent planet. Saturn’s first known natural satellite, Titan was discovered in 1655 by Dutch astronomer Christiaan Huygens, in contrast with several newly discovered moons announced in 2019. The trail on the far right belongs to Iapetus, Saturn’s third largest moon. The radius of painted Iapetus’ orbit is so large that only a portion of it was captured here. Saturn leads Jupiter across the night sky this month, rising soon after sunset toward the southeast, and remaining visible until dawn. via NASA

Wikipedia article of the day for July 6, 2021

Wikipedia article of the day is Lion-class battlecruiser. Check it out: Article-Link Summary: Two Lion-class battlecruisers were built, for the Royal Navy before World War I. Lion served as the flagship of the British Grand Fleet’s battlecruisers during most of the war, and Princess Royal became the flagship of the 1st Battlecruiser Squadron in 1915. The two ships were a significant improvement over their predecessors in terms of speed, armament and armour. They both participated in the Battle of Heligoland Bight in 1914, where Lion sank the German light cruiser Cöln. In the Battle of Dogger Bank in 1915, Lion was badly damaged and Princess Royal scored several hits, one crippling the German armoured cruiser Blücher, which allowed the enemy vessel to be caught and sunk. At the Battle of Jutland in 1916, Lion suffered a serious cordite fire that could have destroyed the ship, and Princess Royal was moderately damaged. They were both put into reserve in 1920, and were sold for scrap a few years later. (This article is part of a featured topic: Battlecruisers of the world.)
