Shortest Day of the Year in Northern Hemisphere?
Tonight starts the winter solstice, it is the first day of winter marked by the shortest day of the year and longest night of the year in the northern hemisphere.
Tuesday December 21 will also see a total lunar eclipse as the Earth casts a shadow on the moon, turning the sky a deep red.
It's a pretty big astronomical event. My question is, why is the winter solstice the shortest day of the year?
What is the scientific explanation of the shortest day of the year in the northern hemisphere?
