Managua vs Aurora

Informations

Managua (Spanish pronunciation: [maˈnaɣwa]) is the capital and largest city of Nicaragua, and the center of an eponymous department. Located on the southwestern shore of Lake Managua and inside the Managua Department, it has an estimated population 1,042,641 in 2016 within the city's administrative limits and a population of 1,401,687 in the metropolitan area, which additionally includes the municipalities of Ciudad Sandino, El Crucero, Nindirí, Ticuantepe and Tipitapa.The city was declared the national capital in 1852.

Previously, the capital alternated between the cities of León and Granada. The 1972 Nicaragua earthquake and years of civil war in the 1980s severely disrupted and stunted Managua's growth. It was not until the mid-1990s that Managua began to see a resurgence.Managua's population is composed predominantly of mestizos and whites who are mainly of Spanish descent, with a minority being of French, Jewish Nicaraguan, German Nicaraguan, Italian, Russian, Greek and Turkish descent.

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.
