Aurora vs Modena

Informations

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.

Modena (UK: , US: , Italian: [ˈmɔːdena] (listen); Modenese: Mòdna [ˈmɔdnɐ]; Etruscan: Mutna; Latin: Mutina) is a city and comune (municipality) on the south side of the Po Valley, in the Province of Modena in the Emilia-Romagna region of northern Italy. A town, and seat of an archbishop, it is known for its car industry since the factories of the famous Italian upper-class sports car makers Ferrari, De Tomaso, Lamborghini, Pagani and Maserati are, or were, located here and all, except Lamborghini, have headquarters in the city or nearby. One of Ferrari's cars, the 360 Modena, was named after the town itself. The University of Modena, founded in 1175 and expanded by Francesco II d'Este in 1686, focuses on economics, medicine and law, and is the second oldest athenaeum in Italy. Italian military officers are trained at the Military Academy of Modena, and partly housed in the Baroque Ducal Palace.

The Biblioteca Estense houses historical volumes and 3,000 manuscripts. The Cathedral of Modena, the Torre della Ghirlandina and Piazza Grande are a UNESCO World Heritage Site since 1997. Modena is also known in culinary circles for its production of balsamic vinegar.Famous Modenesi include Mary of Modena, the Queen consort of England and Scotland; operatic tenor Luciano Pavarotti and soprano Mirella Freni, born in Modena itself; Enzo Ferrari, eponymous founder of the Ferrari motor company; Catholic priest Gabriele Amorth; chef Massimo Bottura; comics artist Franco Bonvicini; the band Modena City Ramblers and singer-songwriter Francesco Guccini, who lived here for several decades.
