Ursa Major At Sky Timelapse, Finland, Pirkkala

Ursa Major (/ˈɜːrsə ˈmeɪdʒər/; also known as the Great Bear) is a constellation in the northern sky, whose associated mythology likely dates back into prehistory. Its Latin name means "greater (or larger) she-bear", standing as a reference to and in direct contrast with nearby Ursa Minor, the lesser bear. In antiquity, it was one of the original 48 constellations listed by Ptolemy (2nd century AD), and is now the third largest constellation of the 88 modern constellations.
Ursa Major is primarily known from the asterism of its main seven relatively bright stars comprising the (historically named) "Charles' Wain", "Big Dipper", "the Wagon" or "the Plough" (among others), with its stellar configuration mimicking the shape of the "Little Dipper".
The general constellation outline often significantly features in numerous world cultures, and frequently is used as a symbol of the north. e.g. As the flag of Alaska. Also the asterism's two brightest stars named Dubhe and Merak (α Ursae Majoris and β Ursae Majoris) can be used as the navigational pointer towards the place of the current northern pole star, Polaris in Ursa Minor.
Ursa Major is visible throughout the year from most of the northern hemisphere, and appears circumpolar above the mid-northern latitudes. From southern temperate latitudes, the main asterism is invisible, but the northern parts of the constellation can still be viewed.
