From today's featured articleEl Tatio is a geothermal field with many geysers located in the Andes of northern Chile at 4,320 metres (14,170 ft) above sea level. It is the third-largest geyser field in the world and the largest in the Southern Hemisphere. The geothermal field has many geysers, hot springs, and associated sinter deposits. The vents are sites of populations of extremophile microorganisms such as hyperthermophiles, and have been studied as an analogue for the early Earth and possible past life on Mars. El Tatio lies at the western foot of a series of stratovolcanoes, part of the Central Volcanic Zone and the Altiplano–Puna volcanic complex, which may be the source of heat for El Tatio. There are no recorded eruptions of the Tatio volcanoes. The field is a major tourism destination. It has been prospected for geothermal power production, but development ceased after a major incident in 2009 when a drilling well blew out. (Full article...)

From today's featured list
The 2nd Division, a division of infantry of the British Army, has numerous orders of battle, which can provide information on the strength of that formation and the equipment used. The 2nd Infantry Division was formed numerous times over a 203-year period. Several formations bore the name, the "2nd Division", from 1809 through to the end of the 19th century. The historian Everard Wyrall, the compiler of the division's First World War official history, only included those formations that fought in the Napoleonic Wars, the Crimean War, and the Second Boer War as being linked with the division that was created in the 20th century and fought in the First World War. That modern formation was created in 1902 and would go to further serve in the Second World War. The first 2nd Division that was formed was a mere 3,900 men strong and did not include supporting weapons such as artillery. In comparison, the 2nd Infantry Division, from the Second World War period, was over 18,000 men strong and supported by 72 artillery pieces and numerous other support weapons. (Full list...)

The ruble is the name of a currency unit in a number of countries in eastern Europe. This one-ruble coin was issued by the Russian Empire in 1771, during the reign of Catherine the Great. It is made of solid copper, weighing just over 1.022 kg (2.25 lb), and was designed to be kept in the imperial treasury as metallic backing for the country's paper-ruble issue. Marginally larger than a standard hockey puck, it is reportedly the largest copper coin ever issued. The coin now forms part of the National Numismatic Collection at the National Museum of American History. Coin design credit: Russian Empire; photographed by the National Numismatic Collection
