A black moon also refers to the new moon phase itself when the moon is positioned between Earth and the sun, making it nearly invisible from our view. The black moon is a new moon in Capricorn, an Earth sign associated with ambition, professional goals, societal structures and authority, according to Thomas.

December 2024 will feature a rare Black Moon on December 30 at 5:27 p.m. ET. This second new moon of the month won't be visible, but its lack of moonlight will create ideal conditions for stargazing and viewing distant celestial objects.

As 2024 concludes, the night sky presents a remarkable celestial event: the black moon. This phenomenon, defined as the second new moon in a single calendar month, occurs infrequently and offers a unique opportunity for skywatchers to witness the heavens under ideal stargazing conditions.
