The Egg Nebula is in a stage of life rarely observed by astronomers.

This false-color coded image shows shells that look like tree rings, along with two mysterious “searchlight” beams shooting out high speed jets of matter.

The shells are created when the red giant star at the center of the Egg Nebula (hidden by a ring of dust) repeatedly blows off gas and plasma as it slowly transforms into a white dwarf star.
