Kampala vs Aurora

Informations

Kampala (UK: , US: ) is the capital and largest city of Uganda. The city proper was estimated to have a population of 1,650,800 people on 31 July 2019 and is divided into the five boroughs of Kampala Central Division, Kawempe Division, Makindye Division, Nakawa Division, and Rubaga Division. Kampala's metropolitan area consists of the city proper and the neighboring Wakiso District, Mukono District, Mpigi District, Buikwe District and Luweero District. It has a rapidly growing population that is estimated at 6,709,900 people in 2019 by the Uganda Bureau of Statistics in an area of 8,451.

9 km2 (3,263.3 square miles). In 2015, this metropolitan area generated an estimated nominal GDP of $13.80221 billion (constant US dollars of 2011) according to Xuantong Wang et al., which was more than half of Uganda's GDP for that year, indicating the importance of Kampala to Uganda's economy. Kampala is reported to be among the fastest-growing cities in Africa, with an annual population growth rate of 4.03 percent, by City Mayors. Mercer (a New York-based consulting firm) has regularly ranked Kampala as East Africa's best city to live in, ahead of Nairobi and Kigali.

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.
