The shape of this nebula published in Astronomy Picture of the Day (APOD) may surprise you. It did me. 

The accompanying explanation on how a circle became a square notes that no one is quite sure what produced this geometric shape. One hypothesis is explored as well as a possible future event.

In any event it is a glory of the great beyond and makes me pause to say thanks for the scientists, engineers and technologists who allow us to see such features of the cosmos.
