Aurora vs Tarbes

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.

Tarbes (French pronunciation: ​[taʁb]; Gascon: Tarba) is a commune in the Hautes-Pyrénées department in the Occitanie region of southwestern France. It is the capital of Bigorre. It has been a commune since 1790. It was known as Turba or Tarba in Roman times. Tarbes is part of the historical region of Gascony. Formerly of strong industrial tradition, Tarbes today tries to diversify its activities, particularly in aeronautics and high tech around the different zones of activities which are increasing.

The recent development of Tarbais beans and other regional specialties also shows a willingness to develop the agri-food industry thus justifying its nickname of "market town". Its 42,888 inhabitants are called Tarbaises and the Tarbais. It is the seat of the diocese of Tarbes-et-Lourdes. The 1st Parachute Hussar Regiment and 35th Parachute Artillery Regiment are stationed in Tarbes.
