The Big Dipper is one of the most easily recognizable asterisms in the night sky, found in the constellation Ursa Major, the Great Bear. The star pattern, formed by the seven brightest stars of Ursa Major, is well-known in many cultures and goes by many other names, among them the Plough, the Great Wagon, Saptarishi, and the Saucepan. The Big Dipper is particularly prominent in the northern sky in the summer, and is one of the first star patterns we learn to identify.

The Ring Nebula, or Messier 57, is a famous planetary nebula located in Lyra constellation, south of Vega, the fifth brightest star in the sky.

The nebula was formed about 4,000 years ago, when the central star, a red giant, ejected a shell of ionized gas in the final stage of its evolution before becoming a white dwarf.

M57 is classified as a bipolar nebula, one whose equatorial rings visibly enlarge the nebula’s structure and give it a symmetric bi-lobed appearance. It is often confused with the Helix Nebula in Aquarius, another famous planetary nebula that has the appearance of a celestial eye.
