Tomorrow will be our last chance to see a blue moon until July of 2015. Of course, blue moons are no bluer than any other full moon -- only rarer. They're anomalous calendrical events that come about because our lunar cycle doesn't quite jibe with our 12 month, solar calendar. By our current definition, blue moons are really just like other full moons except that they happen to fall as a second full moon in a month. That makes them kind of neat, so people write songs about them.
What makes this blue moon particularly special is that it is also the day that Neil Armstrong will be laid to rest.
There's a rare `blue moon' on Friday, a fitting wink to Neil Armstrong by the cosmic calendar.
That's the day of a private service for Armstrong, the first man to walk on the moon, who died last Saturday in Ohio at age 82.
