Later this week, at sunset, you can step outside and witness a display of light and shadow on the Moon that puzzled sky watchers for thousands of years--until Leonardo Da Vinci figured it out.

Very intresting Tugmistress. I have often seen it and wondered but did not investigate it.
Thank you for that.
