Summer Solstice Pictures: From Stonehenge to Carhenge
Cultures around the world have a long history of celebrating the summer solstice.
Summer solstice will be a cause for celebration this weekend, as the date marks the start of summer for people across the Northern Hemisphere.
On June 21—the longest day of the year—the sun will be at its highest point in the sky.
The Earth's tilt is to thank for this demarcation of seasons: Summer solstice occurs when the North Pole is tilted directly toward the sun. (The Southern Hemisphere experiences its summer solstice in December, when the South Pole is directly tilted toward the sun.)
Signifying growth and life, the event has a long history of being recognized as a critical event in the calendar, and many cultures have developed celebrations and rituals to coincide with it.
