Tonight is the longest night of the year, the perfect time to finish your syllabus

Today, December 21, marks the longest night of the year in the Northern Hemisphere, with December 22 being the shortest day. This is due to the Earth's tilt, causing the Northern Hemisphere to be farther from the Sun, resulting in shorter days and longer nights. In contrast, the Southern Hemisphere experiences the longest day. The winter solstice, occurring between December 21-22, marks the Sun's southernmost position, with Jupiter being the brightest in the sky. This shift creates winter in the north and summer in the south.
