Odessa or Odesa (Ukrainian: Оде́са, romanized: Odesa [oˈdɛsɐ] (listen); Russian: Оде́сса, romanized: Odessa [ɐˈdʲesə]; Bulgarian: Оде́са, romanized: Odesa) is the third most populous city of Ukraine and a major tourism center, seaport and transport hub located on the northwestern shore of the Black Sea. It is also the administrative center of the Odessa Oblast and a multiethnic cultural center. Odessa is sometimes called the "pearl of the Black Sea", the "South Capital" (under the Russian Empire and Soviet Union), and "Southern Palmyra".
Before the Tsarist establishment of Odessa, an ancient Greek settlement existed at its location. A more recent Tatar settlement was also founded at the location by Hacı I Giray, the Khan of Crimea in 1440 that was named after him as Hacibey (or Khadjibey). After a period of Lithuanian Grand Duchy control, Hacibey and surroundings became part of the domain of the Ottomans in 1529 and remained there until the empire's defeat in the Russo-Turkish War of 1792.
In 1794, the city of Odessa was founded by a decree of the Russian empress Catherine the Great. From 1819 to 1858, Odessa was a free port—a porto-franco.

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).
