The Helix Nebula (NGC 7293), is a planetary nebula located relatively close to Earth. This structure, situated approximately 655 light-years away in the direction of the Aquarius constellation, is one of the largest planetary nebulae in terms of angular size as seen in the sky. It formed when the central star at its core ejected its outer layers during the final stages of its life. NGC 7293 is regarded as an important observational target for studying the late phases of stellar evolution and the
