| Notes | Perhaps one of the closest planetary nebula to earth at a distance of 450 light years, the Helix is a stunning example of the evolutionary life of a star. The gaseous nitrogen and hydrogen in the 1.5 light year span of the main ring is ionized by UV radiation from the nebula's central star, causing it to glow and reveal its exquisite structure. |
