Some splendid lunar animations

Standard

I’m work­ing on a talk today. At one point it threatened to be inter­est­ing, but I think I’ve got that under con­trol. Something that might spoil that plan though are some lunar anim­a­tions from NASA. You can Dial-A-Moon at their web­site and down­load anim­a­tions of lunar phases and libration.

Libration is inter­est­ing. It’s the wobble in the moon as it gets pulled around in orbit. The down­load­able anim­a­tions bring this out nicely and NASA has gone to some lengths to make them as usable as pos­sible for people. You can down­load the files in vari­ous formats from http://j.mp/dialamoon or watch them via YouTube.
