the article was mostly about the Gorilla Effect, but I was really interested in the odd feature in the imagery. It was right at the limit of resolution, and its not clear if it was just a chance alignment of shadows that looked like a perfect square nestled in a perfect equilateral triangle, (a building surrounded by a wall?) or if it was just an accidental artifact or optical illusion of no physical significance.

Another mystery...It'll be a long time before we go there again.

And there was no additional information, like scale, or an alternate perspective to help make sense of the "object".
