Havana vs Aurora

Informations

Havana (; Spanish: La Habana [la aˈβana] (listen)) is the capital city, largest city, province, major port, and leading commercial center of Cuba. The city has a population of 2.1 million inhabitants, and it spans a total of 781.58 km2 (301.77 sq mi) – making it the largest city by area, the most populous city, and the fourth largest metropolitan area in the Caribbean region.The city of Havana was founded by the Spanish in the 16th century and due to its strategic location it served as a springboard for the Spanish conquest of the Americas, becoming a stopping point for treasure-laden Spanish galleons returning to Spain. The King Philip II of Spain granted Havana the title of capital in 1592. Walls as well as forts were built to protect the old city. The sinking of the U.S. battleship Maine in Havana's harbor in 1898 was the immediate cause of the Spanish–American War.The city is the center of the Cuban government, and home to various ministries, headquarters of businesses and over 100 diplomatic offices.

The governor is Reinaldo García Zapata of the Communist Party of Cuba (PCC). In 2009, the city/province had the third highest income in the country.Contemporary Havana can essentially be described as three cities in one: Old Havana, Vedado and the newer suburban districts. The city extends mostly westward and southward from the bay, which is entered through a narrow inlet and which divides into three main harbors: Mari melena, Guanabacoa and Antares. The sluggish Almendares River traverses the city from south to north, entering the Straits of Florida a few miles west of the bay.The city attracts over a million tourists annually; the Official Census for Havana reports that in 2010 the city was visited by 1,176,627 international tourists, a 20% increase from 2005. Old Havana was declared a UNESCO World Heritage Site in 1982. The city is also noted for its history, culture, architecture and monuments. As typical of Cuba, Havana experiences a tropical climate.

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.
