Antwerp vs Aurora

Informations

Antwerp ( (listen); Dutch: Antwerpen [ˈɑntʋɛrpə(n)] (listen); French: Anvers [ɑ̃vɛʁs] (listen)) is a city in Belgium and the capital of Antwerp province in the Flemish Region. With a population of 520,504, it is the most populous city proper in Belgium, and with a metropolitan population of around 1,200,000 people, it is the second-largest metropolitan region after Brussels.Antwerp is on the River Scheldt, linked to the North Sea by the river's Westerschelde estuary. It is about 40 kilometres (25 mi) north of Brussels, and about 15 kilometres (9 mi) south of the Dutch border. The Port of Antwerp is one of the biggest in the world, ranking second in Europe and within the top 20 globally. The city is also known for its diamond industry and trade. In 2020, the Globalization and World Cities Research Network rated Antwerp as a Gamma + level Global City.

Both economically and culturally, Antwerp is and has long been an important city in the Low Countries, especially before and during the Spanish Fury (1576) and throughout and after the subsequent Dutch Revolt. The Bourse of Antwerp, originally built in 1531 and re-built in 1872, was the world's first purpose-built commodity exchange. It was founded before stocks and shares existed, so was not strictly a stock exchange.The inhabitants of Antwerp are nicknamed Sinjoren (Dutch pronunciation: [sɪɲˈjoːrə(n)]), after the Spanish honorific señor or French seigneur, "lord", referring to the Spanish noblemen who ruled the city in the 17th century. The city hosted the 1920 Summer Olympics.

An aurora (plural: auroras or aurorae), sometimes referred to as polar lights (aurora polaris), northern lights (aurora borealis), or southern lights (aurora australis), is a natural light display in the Earth's sky, predominantly seen in high-latitude regions (around the Arctic and Antarctic). Auroras are the result of disturbances in the magnetosphere caused by solar wind. These disturbances are sometimes strong enough to alter the trajectories of charged particles in both solar wind and magnetospheric plasma. These particles, mainly electrons and protons, precipitate into the upper atmosphere (thermosphere/exosphere).

The resulting ionization and excitation of atmospheric constituents emit light of varying color and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating particles. Precipitating protons generally produce optical emissions as incident hydrogen atoms after gaining electrons from the atmosphere. Proton auroras are usually observed at lower latitudes.
