The winter solstice is an astronomical phenomenon which marks the shortest day of the year in the Northern Hemisphere and the longest day of the year in the Southern Hemisphere when the sun appears at its most southerly position.
It occurs when one of the Earth’s poles has its maximum tilt away from the Sun. It happens twice yearly, once in each hemisphere. In the Northern Hemisphere this is the December solstice and in the Southern Hemisphere, this is the June solstice.
The word “solstice” comes from the Latin solstitium meaning “sun stands still”, when the ‘movement of the sun’s path’ stops briefly. The day and time of the solstice vary each year. In December, the Earth’s the North Pole turns away from the Sun, giving the Southern Hemisphere the most sunlight.
On 21 December 2018, Google Doodle marks winter solstice the shortest day and the longest night of the year when the Earth’s pole has its maximum slope from the Sun. The next summer solstice will take place on June 21, 2019. Read more posts…
