Don’t Miss the Double Shadow Show
The spectacle begins early in the morning, so set your telescope and alarm clock for the best view. Io and Europa, two of Jupiter’s largest Galilean moons, will cross in front of the gas giant almost simultaneously. As they move, their shadows lead the way, creating a breathtaking double-shadow effect on the planet’s surface. Even amateur astronomers can enjoy this event with a modest telescope.
Observing these transits not only offers a beautiful skywatching moment but also lets you witness the dynamic dance of Jupiter’s moons. Check local times for your region to catch this astronomical highlight.
