"The Event: A rare Black Moon, the second new moon of December, occurs Dec. 30 at 5:27 PM EST, visible in America and then Asia, Europe, and Africa on Dec 31, creating exceptionally dark skies for stargazing. What It Means: While the Black Moon itself is invisible, the darker skies offer enhanced visibility of Jupiter, Venus, and prominent constellations like Orion, making it an ideal night for astronomical observation."
