I was getting in my car after work when I noticed the moon -- almost full with just a sliver of blurriness at one edge. It was so breathtaking that I gasped out loud. I love it when it's low in the sky and looks so close. Tomorrow night it will be completely full. More info on space.com's nighttime sky calendar.
