Wow! Yes, I know, this is a repeat image, but Sundays are repeat days, and this image is certainly spectacular enough to be featured as an APOD at least twice!
What creates the illusion that the Moon has rings is the fact that the long narrow cloud bank that passes in front of it consists of two parts: one dense and dark, which seems to cut the face of the Moon in half, and one much thinner, which seems to disappear as it passes in front of the luminous face of the Moon. Therefore the thin part of the cloud bank appears to pass
behind the Moon. Which it clearly doesn't, of course.
