Don’t Miss This Rare Sky Event
Before dawn on Thursday, May 14, 2026, skywatchers will be treated to a rare sight: a cosmic triangle formed by the moon, Saturn, and Mars. This celestial alignment promises a stunning visual as the trio appears low on the eastern horizon.
What to Expect in the Night Sky
The Cosmic Triangle Formation
The moon, Saturn, and Mars will converge in a tight formation, with the moon positioned between the two planets. Here’s what to look for:
- Moon: A razor-thin waning crescent (day 27 of its 29.5-day cycle), with only 8% illumination. It will appear as a faint sliver in the pre-dawn sky.
- Saturn: Visible to the right of the moon, glowing like a bright star.
- Mars: Positioned to the left of the moon, displaying its signature deep red hue.
- Neptune: Also present but not visible to the naked eye.
All three celestial bodies will be less than 20 degrees above the horizon before disappearing into the sunrise glare. For optimal viewing, look east about 45 minutes before sunrise.
Best Time to Watch
The ideal window to observe this alignment is around 4:55 a.m. ET in New York, 4:36 a.m. ET in Boston, or 5:01 a.m. ET in Philadelphia. Timing may vary slightly based on location.
