The word “solstice” comes from Latin, combining “sol” meaning sun and “sistere” meaning stillness. This describes the moment when the sun appears to pause in its motion along the horizon before changing direction.

The December solstice has been celebrated and celebrated by cultures across the globe for centuries, symbolizing change, renewal, and the balance of light and dark.

Understanding the science behind this phenomenon is simple. The Earth’s axis of rotation around the Sun is slightly tilted, about 23.5 degrees. This tilt is responsible for seasonal changes and affects the distribution of sunlight across the Earth. During the December solstice, the North Pole is furthest from the Sun and the South Pole is closest.

Learn the science behind the winter solstice

Earth’s axis tilts

The Earth is not upright in its orbit, but tilted at an angle of about 23.5 degrees. This tilt is why we experience seasons. During the winter solstice in the Northern Hemisphere, the North Pole is furthest from the sun. This means that sunlight reaches this part of the Earth at a very shallow angle, spreading over a larger area, resulting in less direct sunlight.

The shortest path the sun takes across the sky

On the winter solstice, the sun appears to take its lowest and shortest path across the sky. This is because the tilt of the Earth minimizes the height of the Sun. As a result, daylight hours are significantly reduced, resulting in the shortest days of the year.

the longest night of the year

Reduced sunlight naturally means the longest hours of darkness, or night, during the winter solstice. The difference is evident for many areas in the Northern Hemisphere, with some areas near the Arctic Circle experiencing 24 hours of complete darkness.

In short, the winter solstice has profound cultural and symbolic significance. For centuries, civilizations have viewed this turning point as a moment of renewal and hope, marking the gradual return of longer days and brighter skies. On this day we marvel at the natural rhythms that govern our planet and reflect on the enduring balance of light and dark.
