This is a bit old, but on Monday, December 1, 2008, Venus, Jupiter and a crescent moon all lined up perfectly in the sky to create the illusion of a smiley face or a sad face (depending on what hemisphere and region you were looking up at the sky from).

It is a pretty rare event that these heavenly bodies line up so perfectly to form an image in the sky and Jack Horkheimer of the Miami Space Transit Planetarium says the next one won’t happen until November 18, 2052. If you missed this past one though, you can see some wonderful faces in the sky at The Frame photo blog.
