🔭 Astronomical Events

June 15 – 21, 2026

Written by Mia Astrology

This is a transition week in the sky. The Moon grows from a delicate crescent into First Quarter, summer constellations fully rise into dominance in the Northern Hemisphere, and the June Solstice marks a powerful astronomical turning point.

This is a week of balance — light reaching its peak, darkness quietly preparing its return.
