Jupiter's Moon Ganymede to Disappear in Rare Occultation Event Visible Across U.S.
Jupiter's largest moon, Ganymede, is set to pass behind the planet's disk in a rare occultation event visible across the continental United States. This celestial event will begin just after midnight EST on February 7, 2026. Ganymede, which is the largest of Jupiter's Galilean moons, will disappear behind the planet's northwestern limb, an occurrence that can be observed with a telescope. The disappearance will take several minutes due to Ganymede's size, offering a unique viewing opportunity for astronomy enthusiasts. The moon will remain hidden for over three hours, reemerging around 4:15 A.M. MST on February 8. However, its reappearance will be obscured by Jupiter's shadow, making it best visible from the West Coast.
