What’s on your desktop this week? I’ve got the moon.
This image was the APOD for January 2nd. Although it shows a partial lunar eclipse as well as the elusive Blue Moon, the thing that I most like about this image is that it almost looks as though the moon is in front of the clouds. But clearly, that’s an illusion. Who would photoshop the moon in front of the clouds? Nobody but the merest beginner would do that. This must therefore be an authentic optical illusion.
