The moon and Jupiter will be quite a sight in the early morning skies tomorrow.
Sometime before or after sunrise (depending on where you are) on Wednesday, May 17, gas giant Jupiter and its four bright Galilean moons will pass behind a very thin — only 5% illuminated — waning crescent moon as seen from North America. This occultation can best be watched from the western third of the United States and Canada, where at least part of it happens before sunrise. At locations where it occurs in a relatively dark sky, you might be able to watch Jupiter disappear using no optical aid at all — although binoculars will give a better view, and you will need a telescope to follow its moons.
