The M57 Ring Nebula is a planetary nebula located in the constellation of Lyra, about 2,300 light years away from the Earth. The nebula got its name from its resemblance to a ring. A sun-like star at its final stage of evolution releases a gaseous shell into the space. These gases emit vivid colourful light when excited by the radiation of the star. |
