This Wednesday (June 21st), the Northern Hemisphere will experience the Summer Solstice. Marking the onset of a new season, this astronomical event also signifies the longest day of the year. Officially commencing at 8:57 a.m. (Mountain Time) according to the National Weather Service, it offers an intriguing blend of science, history, and culture.
What Occurs During the Summer Solstice?
On the day of the summer solstice, the Sun embarks on its northernmost journey across the sky. This results in:
- The longest stretch of daylight we experience throughout the year
- The shortest night in our calendar
At the peak of the solstice, the Sun is directly above the Tropic of Cancer, reaching its highest point in the sky. This arrangement leads to:
- Maximum daylight hours
- Minimum darkness hours
An intriguing phenomenon occurs around the time of the solstice - the Sun sets more slowly. This is because the farther the Sun sets from due west along the horizon, the shallower the angle of the setting Sun, hence it takes longer to descend.
Cultural Significance of the Summer Solstice
The Summer Solstice has long been recognized and celebrated by cultures worldwide for its significance. Some of these traditions include:
Ancient Egypt: The Summer Solstice coincided with the rising of the Nile River. This event was so critical it marked the beginning of the Egyptian New Year.
Ireland: In previous centuries, hazel branches were cut on solstice eve. These were used for dowsing, a technique for searching for underground resources like gold, water, and precious jewels.
Europe: Many cultures commemorate the solstice with Midsummer celebrations, including gatherings at Stonehenge and the lighting of hilltop bonfires.
