🔭 Astronomical Events
May 11 – 17, 2026
Written by Mia Astrology ✨🌌
This week shifts the sky’s mood beautifully. The Moon thins toward New again, mornings become darker, and planetary viewing continues to strengthen. It’s a quieter week than meteor-peak season, but it’s incredibly rewarding for those who love subtle sky transitions.
Everything below follows verified 2026 lunar cycles and established astronomical patterns.
🌙 Moon Phase This Week
🌘 Waning Crescent → 🌑 New Moon
After Last Quarter on May 9, the Moon continues thinning.
🌑 New Moon — May 16, 2026
At New Moon:
- The Moon is invisible in the night sky
- Evenings are extremely dark
- Ideal conditions for deep-sky observing
✨ Why this matters:
May 15–17 offers some of the darkest skies of the month.
🌌 Deep-Sky Viewing
This is prime galaxy and cluster territory.
Best targets this week:
- 🌌 Virgo Galaxy Cluster
- 🌌 Leo Triplet
- 🌌 Whirlpool Galaxy (M51)
- ✨ Globular Cluster M13 in Hercules (rising higher each night)
- Southern Hemisphere: Milky Way core rising earlier before dawn
If you’ve been waiting for clean, moon-free evenings, this is your opportunity.
🪐 Planet Watch
🌇 After Sunset (Western Sky)
- Venus remains bright and easy to spot
- Mars visible but gradually dimming

30–75 minutes after sunset
Clear western horizon improves visibility.
🌅 Before Sunrise (Eastern Sky)

Pre-dawn sessions are calm, quiet, and incredibly rewarding this week.
