Witness an Astounding Astronomical Event

This evening, the gas giant Jupiter reigns supreme in the constellation Taurus, casting a luminous glow as it sets in the west, making for a spectacular sight! Located just to the right of Alheka (Zeta Tauri), one of Taurus's horn tips, Jupiter shines with a dazzling magnitude of 1.9, effortlessly stealing the spotlight among the stars.

Don't Miss Callisto's Special Appearance!

Tonight is particularly special as Jupiter's moon Callisto prepares to make a close brush with the planet's northern limb! From approximately 9 P.M. to 9:30 P.M. CDT, stargazers will be treated to this rare event. At around 9:20 P.M. CDT, Callisto will be positioned directly north of Jupiter, making this a moment you won’t want to miss!

Optimal Viewing Conditions by Time Zone

If you're observing from the Central time zone in the U.S., you're in for an optimal experience! Meanwhile, East Coast enthusiasts will find Jupiter slipping below the horizon, and those in the Mountain time zone will enjoy the show just after sunset. Yet, everyone across the western skies can still catch action as Io transits from east to west across Jupiter’s disk starting at 9:07 P.M. MDT.

Catch Ganymede and Europa in the Mix!

Keep your eyes peeled as Ganymede makes an appearance just moments after Io, crossing through the dark shadow of Jupiter and becoming visible alongside the gas giant. And while all this excitement unfolds, Europa will be lingering at a distance, sitting far to the west of Jupiter throughout the night.
