When and How to See Summer Solstice
Astronomical events follow precise, predictable celestial mechanics — the alignment of the Sun, Earth, and Moon, or Earth's position in its orbit. That predictability is what lets Summer Solstice 2027 be calculated to the exact date and time years in advance.
Many of these events reward a little preparation: a clear sky, a dark spot away from city lights, and good timing. Eclipses and meteor showers are visible only from certain regions or at certain hours, so it is worth checking visibility for your location. A countdown ensures you set aside the evening before the moment passes — some of these events will not repeat for years.
