Ursa Major

Ursa Major is one of the most well-known constellations in the northern hemisphere, and is also known as the "Great Bear". It is one of the easiest constellations to spot in the sky, and is recognizable for its distinctive shape, which resembles a bear with a long tail.

Within Ursa Major, there is a group of stars known as the Big Dipper or the Plough, which is a familiar sight to many people. The Big Dipper is an asterism, or a recognizable pattern of stars within a larger constellation, and consists of seven stars that form a "ladle" shape.

The stars in Ursa Major have been observed and studied for centuries, and have been used for navigation and celestial mapping by cultures all over the world. In Greek mythology, the constellation was associated with the story of Callisto, a beautiful nymph who was turned into a bear by the goddess Hera.
