Whether you're a skilled astronomer using a high-powered telescope - or an amateur backyard observer, you'll want to know that tonight (August 31st) - represents your chance to see a Blue Moon.

To the uninitiated, a Blue Moon doesn't mean that the orb in the sky looks blue in color;  A Blue Moon refers to the second-showing of a full moon in the same calendar month.

Enjoy this evening's Blue Moon appearance.  The next time that this will occur will be in July 2015.
