Did I mention that you can see this from orbit? Yes, I did.
Did you bother looking at the original nasa/usgs link?
Your original pic is not from NASA, you have it linked from imageshack, so it is not the original...
It's only 100KB, not high quality. Slightly curving lines can appear to be straight.
You can only see 90d edges in your zoomed in pic, it is pixelation. Digital pics are made of little squares with 90d edges. Your low quality image
has large pixels.
What you are seeing are shadows, quite clearly obvious in the large pic.
