I have to imagine capturing an image over five days shows how static something is, not dynamic. Very confusing wording there! Great photo, though.
It's not quite a time lapse. They took 90000 images, but they will be selecting the sharpest and most interesting subset for each section of image, not just smearing them all together.
Maybe static vs. dynamic have different meanings when talking about celestial objects that are billions of years old, 864,000 miles across and a million times the size of the planet you're living on?
I agree! Very odd choice of words indeed. I wonder what semantics they were trying to convey.
