Jupiter’s largest moon Ganymede will briefly disappear in the planet’s shadow at approximately 1:45 a.m. Wednesday, a vanishing act that should be visible to anyone with a small telescope, says Sky and Telescope magazine. Less than a half-hour later, another of Jupiter’s moon — mysterious Europa — will begin crossing the planet’s face, projecting a small dark shadow that also should be visible.

At 1:45 a.m., you’ll find Jupiter 27 degrees above the south-southeast horizon.
