BETHLEHEM, Pa. — Brad Klein reviews the week’s astronomical highlights with Bethlehem’s "Backyard Astronomy Guy," Marty McGuire.
This week marks either the start or the middle of winter in the Northern Hemisphere.
The December solstice is at 10:27 p.m. EST which marks the point at which the Earth’s North Pole is the farthest from the sun.
Days, which have been getting shorter, will now get longer until the summer solstice in June.
