Ganymede's Transit of Jupiter Offers Unique Astronomical Event
On April 16, 2026, Jupiter's largest moon, Ganymede, began its transit across the face of the gas giant, providing a unique astronomical event for observers. The transit started shortly before midnight CDT and continued into the early morning hours of April 17. During this time, Ganymede moved between Jupiter and Earth, taking over three hours to complete the crossing. This event followed the transit of another of Jupiter's moons, Io, which completed its transit earlier in the evening. The transit of Ganymede offered a rare opportunity for astronomers and enthusiasts to observe the dynamics of Jupiter's moons.
