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.

As the next full moon nears, a rare new moon marks the end of 2024 — the black moon. The black moon is a rare celestial phenomena that happens roughly every 29 months or longer. The last one occurred in August of 2022 and the next won't come again until May of 2026.
