The buzz right now centers on an event (or non-event, depending on how you think of it) happening Aug. 23. When an astronomical season, which is about three months long, includes four "new moons" rather than three, the third one is sometimes called a Black Moon. This happens about once every 33 months.

While the spectacular annual Perseid meteor shower peaked around Aug. 12, it generally continues through Aug. 24. With the “Black Moon” occurring tonight, the sky will be extra-dark, giving viewers a better chance of seeing the elusive shooting stars.

A rare black moon is set to appear on Friday, August 22, and it’s sending shockwaves across social media. While astronomers say it’s just a second new moon in a single month, others are linking it to biblical prophecy and end-of-time warnings.
