Friday's 'Blue Moon' Could Actually Look Blue
Sometimes it’s not just a figure of speech.
The term “blue moon” describes a second full moon occurring in one month and, of course, an unusually long span of time.
But if conditions are right, this Friday’s blue moon—the first since August 2012 and the last until January 2018—might subtly look blue in parts of the world. That’s because tiny particles from an unusually active fire season are flooding the atmosphere, and potentially scattering red light to give the moon the impression of a floating blueberry.
