On Friday, January 23rd, there was a triple moon transit on Jupiter. Io, Europa, and Callisto all crossed the planet’s disk and cast shadows on their way. It was a busy night for several hours, but at 11:10 Pacific time the view became almost comical: Io and Europa made tiny ears on either side of the planet while Callisto and its shadow provided eyes and Europa’s shadow provided a mole above the left eye. The polar regions provided a stocking cap and a bushy beard.
The view was through a 12.5″ binocular telescope, which added a 3-dimensional effect that really made the face stand out. The extra mirrors in the binocular scope create an image that’s upside down but correct left-right.
