Kathmandu vs Aurora

Informations

Kathmandu (; Nepali: काठमाडौँ, Nepali pronunciation: [ˈkaʈʰmaɳɖu]) is the capital and largest city of Nepal, with a population of around 1 million. Also known as the city of temples, the city stands at an elevation of approximately 1,400 metres (4,600 feet) above sea level in the bowl-shaped Kathmandu valley in central Nepal. The valley was historically referred to as the"Nepal Mandala" and has been the home of the Newar people, a cosmopolitan urban culture in the Himalayan foothills. The town was the royal capital of the Kingdom of Nepal and hosts palaces, mansions and gardens of the Nepalese aristocracy. It has been home to the headquarters of the South Asian Association for Regional Cooperation (SAARC) since 1985. Today, it's the seat of government of the Nepalese republic, based in 2008, and is a part of the Bagmati Pradesh. Kathmandu is and has been for many years the center of Nepal's history, art, culture, and economy. It has a multi-ethnic population within a Hindu and Buddhist majority.

Religious and cultural festivities form a large part of the lives of people residing in Kathmandu. Tourism is an important part of the economy. In 2013, Kathmandu was rated third among the top ten upcoming travel destinations in the world by TripAdvisor, and ranked first in Asia. The city is regarded as the gateway to the Nepalese Himalayas and home to several world heritage sites: the Durbar Square, Swayambhunath, Boudhanath and Pashupatinath. Kathmandu valley is growing at 4 percent annually according to the World Bank in 2010, which makes it one of the fastest-growing metropolitan areas in South Asia, and the very first place in Nepal to face the unprecedented challenges of rapid urbanization and modernization in a metropolitan scale.Historic areas of Kathmandu were severely damaged by a 7.8 magnitude earthquake in April 2015. Some of the buildings are restored while some stay in the process of reconstruction.

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.
