The phenomenon will be visible on December 31 in Europe, but will not be visible to the naked eye.
Astronomy enthusiasts can look forward to a rare celestial event marking the end of 2024 – a black moon. This phenomenon will occur on December 30th, becoming visible on December 30th for the Americas and on December 31st for Europe, Africa and Asia. Although the event is unique, it will not be visible to the naked eye, as it coincides with the new phase of the Moon.
The Black Moon, like its better-known counterpart, the Blue Moon, has two distinct definitions. While the Blue Moon refers to the third full Moon in a season with four full Moons or the second full Moon in a single month, the Black Moon focuses on new Moons. It’s the third new moon in a season with four new Moons or the second new Moon in a single month. The next Black Moon falls into the second category, explains .
These events are relatively rare, although the “second new moon in a month” variant is more common, occurring every 29 months. In contrast, the “seasonal Black Moon” occurs approximately every 33 months. The most recent Black Moon took place May 19, 2023according to the first definition.
Although the Dark Moons are not visible due to the Moon’s position between the Earth and the Sun – where its illuminated side faces away from us – the event offers an excellent opportunity for stargazing. The absence of light from the Moon during this phase creates a darkest night skyideal for observing stars and other celestial objects.
For those already anticipating upcoming celestial occurrences, the next Blue Moon, defined as two full Moons in a single month, is scheduled for May 31, 2026. The next seasonal Blue Moon, which marks the third full Moon in a season of four full Moons, will occur on May 20, 2027.
