# What is a Solstice?
A solstice is a time when the Earth's rotation and orbit around the Sun cause the seasons to change. In the Northern Hemisphere, the summer solstice is the longest day of the year, while in the Southern Hemisphere, it marks the beginning of winter.

# The Earth's Axis
The Earth's axis is tilted at 23.5 degrees, which causes the seasons to change. During the summer solstice, the Northern Hemisphere tilts towards the Sun, receiving the most sunlight, and marking the beginning of summer. The Southern Hemisphere, on the other hand, tilts away from the Sun, resulting in shorter days.

# Solstice Celebrations
Solstice celebrations take place throughout the day, but the exact moment of the solstice occurs when the Sun is directly above the Tropic of Cancer. This year, it will happen at 4:24 AM ET (1:24 AM PT).

# Stonehenge
Stonehenge, located in Wiltshire, England, is one of the oldest known solstice celebrations. This ancient monument, built over 4,000 years ago, features massive stones arranged in a circle. The stones are carefully aligned with the sunrise on the summer solstice, and thousands of people gather to witness this event every year.
