Today's featured article[edit]Hudson Volcano is a volcano in the rugged mountains of southern Chile. Lying in the Southern Volcanic Zone of the Andes, it was formed by the subduction of the oceanic Nazca Plate under the continental South American Plate. Hudson has the form of a 10-kilometre-wide (6-mile) volcanic caldera filled with ice. The volcano has erupted numerous times in the past 2.5 million years forming widespread tephra deposits, and is the most active volcano in the region. Four large eruptions have taken place in the past 20,000 years: 17,300–17,440 before present (BP), 7,750 BP, 4,200 BP, and in 1991. The 7,750 BP eruption was among the most intense volcanic eruptions in South America during the Holocene, devastated the local ecosystem and may have caused substantial shifts in human settlement and lifestyle. During the 1991 eruption, volcanic ash covered a large area in Chile and Argentina, and was deposited as far as Antarctica. The last eruption was in 2011. (Full article...)

Today's featured picture[edit]The mango is an edible stone fruit produced by the tropical tree Mangifera indica. It originated from the region between northwestern Myanmar, Bangladesh, and northeastern India, and is now cultivated across the world, having been introduced to East Africa by Arab and Persian traders in the 9th to 10th centuries and spread further into other areas around the world during the European colonial era. Ripe mangoes vary according to cultivar in size, shape, color, and sweetness. They have a waxy, smooth, and fragrant skin, which is variously yellow, orange, red, or green, and feature a single flat, oblong pit that can be fibrous or hairy on the surface. The fruits may be somewhat round, oval, or kidney-shaped, ranging from 5 to 25 centimetres (2 to 10 inches) in length and from 140 grams (5 ounces) to 2 kilograms (5 pounds) in weight. It is used in culinary products around the world. The mango is the national fruit of India and M. indica is the national tree of Bangladesh. This photograph shows two mangoes grown in Brazil, one whole and one sectioned. The picture was focus-stacked from 12 separate images.Photograph credit: Ivar Leidus
