1870 CANADA (Alberta / Northwest Territories) - Stars and Aurora Borealis in Buffalo National Park

Located in northeastern Alberta and southern Northwest Territories, Wood Buffalo National Park is the second-largest national park in the world (after Northeast Greenland National Park), an UNESCO World Heritage Site since 1983, but also the world's largest dark sky preserve. A dark sky preserve is an area, usually surrounding a park or observatory, that is kept free of artificial light pollution.

1452 NORWAY (Svalbard) - An aurora borealis seen from Svalbard archipelago

Nature gives us a lot of amazing performances, but none is so impressive, mysterious and beautiful as the aurora, a show of light and color that can be seen on the sky of the Arctic and Antarctic regions. Those who lived this experience say it can't be compared with anything in the world, and the photos seem to give them right. Scientifically speaking, an aurora is a natural light display in the sky, caused by charged particles, mainly electrons and protons, entering the atmosphere from above causing ionisation and excitation of atmospheric constituents, and consequent optical emissions. When it occurs in the northern hemisphere (from September to October, and from March to April), the phenomenon is known as the aurora borealis (or the northern lights), a term originally used by Galileo Galilei, referring to the Roman goddess of dawn, Aurora, and to the Titan who represent the winds, Boreas.
