Here comes the cold and dark: The winter solstice, the shortest day of the year in the Northern Hemisphere, occurs early Wednesday morning.
The winter solstice comes about each year when the Northern Hemisphere is tilted the furthermost from the sun, decreasing the amount of energy that reaches Earth. The solstice marks the astronomical start of winter, whereas, in the Southern Hemisphere, December 21 marks the start of summer.
Further, on the winter solstice, places falling north of the equator have shorter than 12 hours whereas locations on the south of the equator have lengthier days; more than 12 hours, according to AccuWeather.
The occasion is a cause for celebration in some regions around the world. The most well-known solstice celebration occurs at the prehistoric Stonehenge ruins in Wiltshire, England, where druids, pagans and others come together to mark the event.
“Solstices and equinoxes are typically used to denote either the beginnings of the seasons or the centre points of the seasons,” says Rick Kline, Data manager, Spacecraft Planetary Imaging Facility at Cornell University, New York.
“Christmas, Hanukkah, Kwanzaa and other holidays have arisen out of the solstices, equinoxes and the midpoints between them,” he adds.
