So, apparently we saw an actual real live blue moon on New Year's Eve, how exciting! I must admit, I made James take a photo of it because it was a blue moon before I actually had any idea what one was.. I just saw something in my RSS feeds from National Geographic or New Scientist that it was one! I did think it was particularly bright, it seemed like dusk kind of darkness even at midnight! It turns out that blue moons aren't actually anything to do with the moon being blue at all, it's just a name given to the second full moon that occurs in a single month, which is pretty rare (only every 2 and a half years).. how bizarre! If you're interested, wikipedia thinks it's derived from the Old English word belewe, which can mean either "blue" or "betrayer". Apparently "betrayer moon" was a term that could have been used to refer to a disconcerting extra full moon in late winter, that fooled people into starting Lent a little too early. The clergy would have to tell people that it was a fake imposter Lent moon, instead of the genuine article! If you weren't interested, it's too late now, sorry.
