Editor's Comments: Please note that the middle image is the original photograph AS17-134-20506. The top and bottom images have been color enhanced to demonstrate the anomalies more clearly. Detractors might suggest that the shape behind the backdrop is simply a lens flare. (Lens flare occurs when light from a strong source – the sun or studio lights – hits the front element of the lens and is " bounced" around between elements in the lens barrel.) The result is lens flare in the image.
But that cannot be the case here because 1) lens flares do not have dimension – the object has recorded on film with a highlight at the top nearest the light source, and with graduated shading away from the light. 2) the camera used for these images was allegedly a Hasselblad with a pentagonal leaf shutter that would not produce a sphere-like result. For more on these anomalous objects please see the detailed analyses in Jack White's later study set: NASA do(o)med? Look up in the sky Chapters 1-8.
