If you have ever heard the phrase "once in a blue moon," you might have wondered if there is an actual blue lunar body in our wonderous world somewhere. In fact, there is, but it isn't really blue. The term refers to the occurrence of two full moons within one calendar month, and Friday, August 31st, you'll be able to catch it twice.
Anthony Cook, an astronomer at the Griffin Observatory, explained how and when to catch the moon. First, you'll be able to see it Friday morning between 6:30 a.m. and 7:00 a.m. on the West Coast, and then again when it comes into view at around 7:13 p.m. Although the phenomenon may not be noteworthy enough to change your schedule to see it, most will be able to take a look at one time or another if they look at the sky.
Although the moon isn't actually blue, there is a chance that it might be rather orange tomorrow when it shows itself, but Cook said that it would most likely simply be a very bright shade of white. He said that there was "nothing unusual really" about the blue lunar body, adding, "It will look like the usual moon."
Oddly, there are some atmospheric conditions that could make the blue seem to be blue, but they have nothing to do with the actual blue moon phenomenon. The occurrence is fairly rare. The last time one was present was December of 2009. "The next time will be on July 31, 2015," Cook said.
It is likely that if the moon does turn orange, or blue or any other color, that someone will announce that it's the end of the world. However, don't be alarmed. The end isn't here...yet.
