The most famous celestial bond, except for the rings of Saturn, is the Ring Nebula or also known as M57. The Ring Nebula is 2,000 light years away and as seen on Earth the nebula looks like a donut-like ring wrapped around the middle of a football shaped cloud of glowing gas. It’s about one light year across and the glowing light the Ring Nebula produces is not coming from the planets but rather from the hot central star ionizes atoms in the gas forming intense ultraviolent light. As seen through the telescope, the reddish color of the outer ring is coming from the nitrogen and sulfur, the cyan color of the inner rings is coming from the glow of the hydrogen, and the blue color in the center is ionized helium.
