🔭 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
• Jupiter steady and brilliant

Best viewing window:
 30–75 minutes after sunset

Clear western horizon improves visibility.

🌅 Before Sunrise (Eastern Sky)

• Saturn continues rising earlier each morning
• Thin crescent Moon visible briefly before New Moon

Best window:
 60–90 minutes before sunrise

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