In 2025, Saturn will host a series of rare transits of its largest moon, Titan, casting shadows across the planet's surface. These events, occurring roughly every 16 days, offer a unique spectacle for astronomers and skywatchers.
The transits began on May 31 and will continue on July 2, July 18, August 3, August 19, September 4, September 20, and October 6. These events are best viewed in the early morning hours with a telescope magnifying at least 200x.
The duration of each shadow crossing varies, decreasing as the year progresses, with the final transit on October 6 being very brief. This alignment is particularly notable due to Saturn's ring plane crossing, which happens approximately every 15 years. Skywatchers should consult astronomy software and aim for clear skies to witness this rare celestial event, with the next similar alignment expected around 2040.
