Have You Ever Seen a Black Moon? Neither Have We, but One Is Coming This Weekend

Here is a 200-word summary of the news article: A "black moon" is set to occur this weekend, though it's a rare lunar event that most people have never witnessed. Unlike other moon phases, a black moon refers to the absence of a new moon, which happens when there are two new moons in a single calendar month. This phenomenon is extremely uncommon, occurring once every 32 months on average. While a black moon is not visible to the naked eye, as the moon is not illuminated, it marks an intriguing astronomical event. The last black moon took place in March 2014, and the next one won't occur until 2024. Experts note that a black moon has no significant impact on the Earth or human activities, despite some misconceptions. It is simply a rarely observed lunar cycle that occurs when the moon's orbit aligns with the Sun and Earth in a particular way. Though a black moon may not be an awe-inspiring sight, it represents a unique astronomical occurrence that is worth acknowledging for those with an interest in the celestial world.
