Winter Solstice Time

While most of you are celebrating the end of exams and the change of semesters, it's also time for a change of seasons, brought to us by astronomical science, not the academic calendar. The winter solstice takes place at 12:30 a.m., EST, December 22, 2011, making tonight the longest night of the year and tomorrow the shortest day. Then every day gets (literally) brighter as winter unfolds. For a quick and very enjoyable review of how the winter solstice comes about, try this short YouTube video set to music.
