Astronomy Picture of the Day - Halo of the Cat's Eye

Explanation: What created the unusual halo around the Cat's Eye nebula? No one is sure. What is sure is that the Cat's Eye Nebula (NGC 6543) is one of the best known planetary nebulae on the sky. Although haunting symmetries are seen in the bright central region, this image was taken to feature its intricately structured outer halo, which spans over three light-years across. Planetary nebulae have long been appreciated as a final phase in the life of a Sun-like star. Only recently however, have some planetaries been found to have expansive halos, likely formed from material shrugged off during earlier puzzling episodes in the star's evolution. While the planetary nebula phase is thought to last for around 10,000 years, astronomers estimate the age of the outer filamentary portions of the Cat's Eye Nebula's halo to be 50,000 to 90,000 years.

what I find interesting is the overlapping ring formation in the middle.

I can visualize so many alternate dimensions that the ring-shaped phenomenon could be a doorway to . . .

If we’re allowed to make requests in Heaven as to what we’d like to do, I know what mine would be.

((Ducking quickly, in the event that any fanatics, with their dead-absolute certainty that Heaven will be an eternal church service, happen upon this thread.))

Are they sure it’s not a mote?

Is that two galaxies colliding?
Maybe both galaxies have black holes at the center, and they are swallowing each other, thus the strange effects.

It looks like it could be a binary star system where one of the pair is going supernova.
