Tonight’s full moon rises at 6:40 and the cloud deck could break after midnight. Native Americans referred to it as the Full Cold Moon. A full moon, reflecting off a snow surface, increases “moonlight.” As noted in a previous column, Parade Magazine’s columnist, David Levy, filed an article, “Why We Have A Moon.” Levy took a “stab” at answering the question: How did the moon get here? He explained Earth had a “bad day” almost 4½ billion years ago when the planet was spurting volcanoes. The planets were closer; the moon was 10,000 miles away and rotated faster, with a day lasting just 10 hours. With a 24-hour day, the moon is sliding away at about 3 feet every century and is now 240,000 miles out. Fastcast: Returning showers.
