December’s Astronomical Occultations
So what in blazes is an astronomical occultation?

When it involves the Sun and Moon, we just call it an eclipse. However, astronomers, not those dealing with the occult, call such an event an occultation. This month of December offers astronomers an unusual series of occultations involving Jupiter’s moons, Io, Europa and Ganymede. Learn more about it in the Astrocast.TV vodcast.
