Informations

Marseille ( mar-SAY, also spelled in English as Marseilles; French: [maʁsɛj] (listen), locally [maχˈsɛjə] (listen); Occitan: Marselha [maʀˈsejɔ, -ˈsijɔ]) is the prefecture of the department of Bouches-du-Rhône and region of Provence-Alpes-Côte d'Azur in France. It is located on the coast of the Gulf of Lion, part of the Mediterranean Sea, near the mouth of the Rhône. Marseille is the second largest city in France, covering an area of 241 km2 (93 sq mi) and had a population of 870,018 in 2016. Its metropolitan area, which extends over 3,174 km2 (1,225 sq mi) is the third-largest in France after those of Paris and Lyon, with a population of 1,760,653 as of 2017, or 3,100,329 (2019) by the broader Eurostat definition of metropolitan region. Its inhabitants are called Marseillais. One of Europe's oldest cities, founded around 600 BC and known to the ancient Greeks as Massalia (Greek: Μασσαλία, romanized: Massalía) and Romans as Massilia. Marseille has been a trading port since ancient times. In particular, it experienced a considerable commercial boom during the colonial period and especially during the 19th century, becoming a prosperous industrial and trading city. Nowadays the Old Port still lies at the heart of the city where the manufacturing of soap, its famous savon de Marseille, began some 6 centuries ago. Overlooking the port is the Basilica of Notre-Dame-de-la-Garde or "Bonne-mère" for the people of Marseille, a Romano-Byzantine church and the symbol of the city.

Inherited from this past, the Grand Port Maritime de Marseille (GPMM) and the maritime economy are major poles of regional and national activity and Marseille remains the first French port, the second Mediterranean port and the fifth European port. Since its origins, Marseille's openness to the Mediterranean Sea has made it a cosmopolitan city marked by cultural and economic exchanges with Southern Europe, the Middle East, North Africa and Asia. In Europe, the city has the third largest Jewish community after London and Paris.In the 1990s, the Euroméditerranée project for economic development and urban renewal was launched. New infrastructures and renovations were carried out in the 2000s and 2010: the tramway, the renovation of the Hôtel-Dieu into a luxury hotel, Le Silo, the expansion of the Velodrome stadium, the CMA CGM Tower, and other quayside museums such as the Museum of Civilisations of Europe and the Mediterranean (MuCEM). As a result, Marseille now has the most museums in France after Paris. The city was named European Capital of Culture in 2013 and European Capital of Sport in 2017. Additionally, Marseille hosted matches at the 1998 World Cup and Euro 2016. It is also home to several higher education institutions in the region, including the University of Aix-Marseille.

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.
