Caracas vs Aurora

Informations

Caracas (, Spanish: [kaˈɾakas]), officially Santiago de León de Caracas, abbreviated as CCS, is the capital and largest city of Venezuela, and the centre of the Metropolitan Region of Caracas (or Greater Caracas). Caracas is located across the Guaire River at the northern portion of the country, within the Caracas Valley of the Venezuelan coastal mountain range (Cordillera de la Costa). The valley is near the Caribbean Sea, separated from the coast by a steep 2,200-metre-high (7,200 ft) mountain range, Cerro El Ávila; to the south there are more hills and mountains. The Metropolitan Region of Caracas has an estimated population of almost 5 million inhabitants. The middle of the city remains Catedral, situated near Bolívar Square, although some consider the center to become Plaza Venezuela, located at the Los Caobos region.

Businesses in town include service companies, banks, and malls. Caracas has a mostly service-based market, besides some industrial action in its metropolitan area. The Caracas Stock Exchange and Petróleos de Venezuela (PDVSA) are headquartered in Caracas. PDVSA is the largest company in Venezuela. Caracas is also Venezuela's cultural capital, with many restaurants, theaters, museums, and shopping centers. Caracas has some of the tallest skyscrapers in Latin America, like the Parque Central Towers. The Museum of Contemporary Art of Caracas is one of the most important in South America.Caracas has among the highest per capita murder rates in the world, with 111.19 homicides per 100,000 inhabitants.

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.
