Kabul vs Aurora

Informations

Kabul (Pashto: کابل, romanized: Kābəl; Dari: کابل, romanized: Kābol) is the capital and largest city of Afghanistan, situated in the eastern section of the country. It is also a municipality, forming part of the greater Kabul Province, and divided into 22 districts. Based on estimates in 2020, the population of Kabul is 4.222 million, which includes all the significant ethnic groups of Afghanistan. Afghanistan's only city with a population of over 1 million, Kabul serves as its political, cultural and economical center. Rapid urbanization has made Kabul the world's 75th biggest city.Kabul is situated high up in a narrow valley between the Hindu Kush mountains, with an elevation of 1,790 metres (5,873 ft) making it one of the greatest capitals in the world. The city is said to be over 3,500 years old, said since at the time of the Achaemenid Empire. Located at crossroads in Asia - approximately halfway between Istanbul in the west and Hanoi in the east - it's in a strategic location along the trade routes of South and Central Asia, and a key location of the historical Silk Road. It has been part of the Achaemenids followed by the Seleucids, Mauryans, Kushans, Kabul Shahis, Saffarids, Samanids, Ghaznavids, Ghurids, Khwarazmians, Qarlughids, Khaljis, Timurids, Mughals, and Hotaks, until eventually becoming part of the Durrani Empire (also known as the"Afghan Empire") in 1747.

Kabul became the capital of Afghanistan in 1776, during the reign of Timur Shah Durrani, the son of Ahmad Shah Durrani. From the early 19th century, the British occupied the city, but after launching foreign relations, they were forced to withdraw all forces from Afghanistan. The city was occupied by the Soviets in 1979 but they too abandoned it after the 1988 Geneva Accords were signed. A civil war in the 1990s involving various rebel groups destroyed much of the city, leading to many casualties. From late 2001 the city has been continuously rebuilt.Kabul is well known for its gardens, bazaars, and palaces, well known examples being the Gardens of Babur and Darul Aman Palace. It was also formerly a mecca for young western hippies. Despite frequent terrorist attacks in the city, mainly by Taliban insurgents, the city continues to develop and was the fifth largest city in the world as of 2012.

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.
