When the sum rose this morning it was on the shortest day of the year. Now the days up here in the Northern Hemisphere will slowly start to lengthen again. At first at a minute or two a day, but gradually a few more minutes around spring time. Then as the Summer solstice approaches the number of minutes slows down. Finally after that the process goes into reverse and the days begin to wane again. So the great cycle of light and dark tumbles along North and South. Only on the equator are day and night lengths balanced out. The cause? Earth is tipped at an angle, so for six months of the year one half of the planet gets more light than the other (which also proves the Earth is a globe).
Happy Solstice everyone!
