Tonight's Sky for January 23: Triple Galalean Moon Shadows on Jupiter


For people who own a telescope, this is an event worth marking on the calendar as, beginning at 10:11pm EST (add an hour for every time zone West you live), three of the four Galalean Moons of Jupiter will cast a shadow on the planet's surface. To see this event, a telescope and a high power magnification is a must as the moons' shadows are tiny when compared to the king of the planets. During the course of the event, one will be able to see all three tiny shadows transit the planet's face before disappearing back into the blackness of space.
