Union gunboats bombarding Confederate defenses
Union gunboats bombarding Confederate defenses

The Battle of Grand Gulf was fought on April 29, 1863, during the American Civil War. Union Army forces commanded by Ulysses S. Grant had failed several times to bypass or capture the Confederate-held city of Vicksburg, Mississippi. Grant decided to move his army south of Vicksburg, cross the Mississippi River, and then advance on the city. A Confederate division under John S. Bowen prepared defenses—Forts Wade and Cobun—at Grand Gulf, Mississippi. To clear the way for a Union crossing, seven ironclad warships from the Mississippi Squadron of the Union Navy commanded by Admiral David Dixon Porter bombarded the Confederate defenses at Grand Gulf. Union fire silenced Fort Wade, but the overall Confederate position held. Grant decided to cross the river elsewhere. The next day, Union forces crossed the river at Bruinsburg, Mississippi. The position at Grand Gulf was abandoned and became a Union supply point. The Grand Gulf battlefield is preserved in Grand Gulf Military State Park. (Full article...)

Arsenal Women Football Club have played 36 domestic league seasons and remained in the English top flight since joining in 1992. Based in London, they are the most successful club in English women's football. They formed in 1987, 100 years after the inception of the Arsenal men's team, and were an amateur side for over a decade until the team became semi-professional in 2002. During the 1990s and 2000s, under the management of Vic Akers and other successive coaches, Arsenal experienced an unprecedented period of success dominating English competitions with no sustained opposition. Domestically, Arsenal have won 15 league titles, 14 FA Cups, 17 league cups and five FA Community Shields; the club holds the most titles of each individual domestic competition. Arsenal are the only English side to have won Europe's continental women's football competition, the UEFA Women's Champions League (formally the UEFA Women's Cup), after the club defeated the Swedish side Umeå in the 2007 final.

Sphalerite

Sphalerite is a sulfide mineral with the chemical formula (Zn,Fe)S. It is found in a variety of deposit types, and is found in association with galena, chalcopyrite, pyrite (and other sulfides), calcite, dolomite, quartz, rhodochrosite, and fluorite. Sphalerite is an important ore of zinc, with around 95 percent of all primary zinc extracted from its ore. Due to its variable trace-element content, sphalerite is also an important source of several other metals such as cadmium, gallium, germanium and indium. The zinc in sphalerite is also used to produce brass. This sample was extracted in Creede, Colorado, and features black tetrahedral crystals of sphalerite up to 8 mm (0.31 in) in size, with minor chalcopyrite and calcite, in a 4.5 cm × 3.0 cm × 2.0 cm (1.77 in × 1.18 in × 0.79 in) matrix. This photograph was focus-stacked from 125 separate images.
