The Helix Nebula (NGC 7293), often referred to as the "Eye of God," is one of the closest and most studied planetary nebulae to Earth, located about 655 light-years away in the constellation Aquarius.

Its structure is a complex, three-dimensional arrangement resulting from the late-stage evolution of a Sun-like star.

High-energy ultraviolet radiation emitted by this central remnant energizes and ionizes the surrounding shell of expelled gases, causing them to glow vividly.
