According to the description of compounds involved and other factors it makes a bit more sense.  Do you think this is reasonable?

The reason this image was so confusing is because planetary Nebulae form around dying stars. During the red giant phase of a star’s life, the star flings off its outer layers of gas, forming an expanding shell around itself, while it gradually cools to become a white dwarf.

The expanding shell is the planetary nebula, and usually you’d expect to see the star in the centre of the pretty gas cloud. But in this image, you can clearly see a star in between the two clouds, so you’d assume – as astronomers did – that this was two objects each forming around their own, neighbouring star.

What happens when we assume? 😉  You know the rest.  Just kidding.  We are glad they figured it out and on with more examination of this crazy cool nebula.
