The Gods Themselves Covers

The covers of The Gods Themselves are strange. I can understand this as the images of this book are either not that interesting or almost impossible, but some of these are on the verge of bizzare.

Is this in 3D or do they just want to give people headaches when they look at this cover.

I just finished reading this book and I really don't have any idea what the image on this next cover is.  So far as I remember there are no air battles in The Gods themselves though technically I suppose there are space shuttles of some type as there are people on the moon.
