Today's featured article

This star symbolizes the featured content on Wikipedia.

Each day, a summary (roughly 975 characters long) of one of Wikipedia's featured articles (FAs) appears at the top of the Main Page as Today's Featured Article (TFA). The Main Page is viewed about 4.7 million times daily.

TFAs are scheduled by the TFA coordinators: Wehwalt, Dank, Gog the Mild and SchroCat. WP:TFAA displays the current month, with easy navigation to other months. If you notice an error in an upcoming TFA summary, please feel free to fix it yourself; if the mistake is in today's or tomorrow's summary, please leave a message at WP:ERRORS so an administrator can fix it. Articles can be nominated for TFA at the TFA requests page, and articles with a date connection within the next year can be suggested at the TFA pending page. Feel free to bring questions and comments to the TFA talk page, and you can ping all the TFA coordinators by adding "{{@TFA}}" in a signed comment on any talk page.

From today's featured article

Huaynaputina is a volcano in a volcanic plateau in southern Peru. Lying in the Central Volcanic Zone of the Andes, it was formed by the subduction of the oceanic Nazca plate under the continental South American plate. Huaynaputina is a large volcanic crater, lacking an identifiable mountain profile, with an outer stratovolcano and three younger volcanic vents within an amphitheatre-shaped structure that is either a former caldera or a remnant of glacial erosion. The volcano has erupted dacitic magma. In the Holocene, Huaynaputina has erupted several times, including on 19 February 1600 – the largest eruption ever recorded in South America. Witnessed by people in the city of Arequipa, it killed at least 1,000 people in the region, wiped out vegetation, buried the surrounding area with 2 metres (7 feet) of volcanic rock and damaged infrastructure and economic resources. The eruption caused a volcanic winter and may have played a role in the onset of the Little Ice Age. Floods, famines, and social upheavals resulted, including a probable link with the Russian Time of Troubles. (Full article...)

From tomorrow's featured article

At an outdoor demonstration in Riesa, Germany, six Tesla workers carry a banner that reads "Tesla Workers gegen Faschismus" ("Tesla workers against fascism"). There is an IG Metall flag in background, and also on the banner itself. The faces of people holding the banner are blurred.

Tesla has labor disputes in the United States, Germany and Sweden, including an ongoing strike in Sweden. Elon Musk, the CEO of Tesla, has expressed his opposition to unions on Twitter (now called X). These tweets are currently under scrutiny by US courts to determine whether they are protected free speech or unlawful. All unionization efforts at the Tesla Fremont Factory and Gigafactory New York in the United States have been unsuccessful. In Germany, Gigafactory Berlin-Brandenburg and Tesla Automation have elected works councils, but they have not signed collective bargaining agreements with the German trade union IG Metall (members pictured). The Gigafactory Berlin-Brandenburg works council is divided into pro-union and anti-union factions. In Sweden, mechanics who are members of the trade union IF Metall have been on strike since October 27, 2023, making it the longest strike in Sweden since 1938. The strike has since spread, with other Swedish, Danish and Norwegian unions calling for solidarity strikes. (Full article...)

The Virgo interferometer is a large-scale scientific instrument near Pisa, Italy, for detecting gravitational waves. The detector measures minuscule length variations in its two 3-kilometre (1.9-mile) arms induced by the passage of gravitational waves. The project, named after the Virgo galaxy cluster, was first approved in 1992 and construction was completed in 2003. After undergoing important upgrades between 2011 and 2016 (during which LIGO made the first detection of gravitational waves), Virgo made its first detection on 14 August 2017. This was followed by the detection of GW170817, the only gravitational wave also observed with classical methods (optical, gamma-ray, X-ray and radio telescopes) as of 2024. Virgo is managed by the Virgo Collaboration, gathering 940 members in 20 countries, in cooperation with similar detectors such as LIGO and KAGRA. (Full article...)
