SMS Prinzregent Luitpold was the fifth and final vessel of the Kaiser class of battleships of the Imperial German Navy. Prinzregent Luitpold's keel was laid in October 1910 at the Germaniawerft dockyard in Kiel. She was launched on 17 February 1912 and was commissioned into the navy on 19 August 1913. Prinzregent Luitpold was assigned to the III Battle Squadron of the High Seas Fleet for the majority of her career; in December 1916, she was transferred to the IV Battle Squadron. Along with her four sister ships, Kaiser, Friedrich der Grosse, Kaiserin, and König Albert, Prinzregent Luitpold participated in all of the major fleet operations of World War I, including the Battle of Jutland on 31 May – 1 June 1916. The ship was also involved in Operation Albion, an amphibious assault on the Russian-held islands in the Gulf of Riga, in late 1917. After Germany's defeat in the war and the signing of the Armistice in November 1918, Prinzregent Luitpold and most of the capital ships of the High Seas Fleet were interned by the Royal Navy in Scapa Flow. Prinzregent Luitpold was scuttled in 1919, raised in 1931 and subsequently broken up for scrap in 1933. (Full article...)

A lava lake at Mount Nyiragongo, a volcano found in Virunga National Park in the Democratic Republic of the Congo. Lava lakes, which can form in three different ways, are large volumes of molten lava, usually basaltic, contained in a volcanic vent, crater, or broad depression. Persistent lava lakes such as the one at Nyiragongo, which is the largest to appear in recent times, are rare.
