The city was later occupied by the Dutch and the British, with the Kingdom of Cochin becoming a princely state.

The city was ranked the sixth best tourist destination in India according to a survey conducted by the Nielsen Company on behalf of the Outlook Traveller magazine. In October 2019, Kochi was ranked seventh in Lonely Planet's list of top 10 cities in the world to visit in 2020.

Kochi was one of the 28 Indian cities among the emerging 440 global cities that will contribute 50% of the world GDP by the year 2025, in a 2011 study done by the McKinsey Global Institute. In July 2018, Kochi was ranked the topmost emerging future megacity in India by global professional services firm JLL.Kochi is known as the financial, commercial and industrial capital of Kerala. It has the highest GDP as well as the highest GDP per capita in the state. The city is home to the Southern Naval Command of the Indian Navy and is the state headquarters of the Indian Coast Guard with an attached air squadron, named Air Squadron 747.

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.
