"If you now study the ring nebulae of the heavens you can see numerous examples of these dying suns. Many of them are shown in these pages. The Owl nebula is a very interesting example of an "unwinding" sun. It has a big hole clear through it. The Ring nebula in Lyra is also interesting to note because what was left of a sun regenerated at the center to repeat throwing off rings until nothing is left." [Atomic Suicide, page 166]
