The Helix nebula is a planetary nebula located in the constellation Aquarius. Discovered by Karl Ludwig Harding, this object is one of the closest of all the bright planetary nebulae to Earth at 653 light years. The Helix Nebula formed by an intermediate to a low-mass star, which sheds its outer layers near the end of its evolution. Gases from the star in the surrounding space appears from Earth's perspective, as a a helix structure. The remnant central stellar core of the planetary nebula, is destined to become a white dwarf star.
