In Astrophotography, post processing is everything, but that doesn't necessarily mean inventing data where there was none. Sometimes, it's more about greatly enhancing what little data is there. It's also not unusual to crank the saturation WAY up to bring out the colors that were in the original image, but not visible or maybe just barely visible.
There may be many elements of truth to the post, but it could be that some elements are incorrect, whether that's due to human error or maliciousness, we'll probably never know.

This.
Sure they use Photoshop, any professional that works with an image uses it.
We use Photoshop as the last step in our image production of aerial photography. We never go above 18,000 feet and that is pretty rare. 90% or our images are below 5,000 feet, certainly not light years away like NASA. We have to adjust the curves and color balance of virtually every image from the mapping camera. Even the oblique angle stuff we shoot with a Nikon D3 is tweaked for color and contrast to make it look better. It does not change the fundamentals of what the picture is showing.
