On the night of December 31, 2024, residents of Russia will have the rare opportunity to observe what is known as the 'Black Moon', where the Moon will become completely invisible, appearing only as darkness against the night sky. According to experts from Novosibirsk State University (NSU), the celestial event will occur at 03:26 local time, marking the second new moon of the month and offering enthusiasts unique skies just as they celebrate the arrival of the new year.
Alfiya Nesterенко, head of the astrophysical automated complex at NSU, explained how this phenomenon manifests. "Typically, the Moon goes through four phases each month: new moon, first quarter, full moon, and last quarter. The unique aspect of this December is the Moon will effectively enter what could be described as the 'fifth' phase for the month – meaning December 31 will see the occurrence of the second new moon," she elaborated.
The occurrence of two new moons within one calendar month is relatively rare, aligning with astronomical events only 3–4 times per century. Historical records show such events have taken place previously—most recently, during the 20th century's 1910, 1929, 1967, and 1986 years.
While the event may draw interest, it poses specific challenges for casual observers. Nesterensko noted, "The new moon is not visible to the naked eye, even for those who know its exact location in the sky. For one to catch even the smallest glimpse, they would need exceptional patience, advanced telescopes, and specialized cameras aimed at the specific spot where the Moon resides, which is ineffective during the new moon's phase due to its alignment."
Further complicate efforts, the lack of visibility means star enthusiasts must rely on other celestial wonders to enjoy the night sky. Experts at NSU claimed, "To see even the faintest part of the Moon, it's possible only if there's a flash from an impacting meteorite — such events occur about every hour,” they noted, emphasising the need for preparation and devotion to the pursuit of viewing this elusive phenomenon.
Despite the challenges presented by the 'Black Moon', the night sky will still hold numerous delights for stargazers. Experts recommend observing star clusters, distant galaxies, and asteroids as they become visible when the Moon's light is absent. The constellation Orion, easily recognizable by its distinct shape, will be prominent, accompanied by the bright planet Jupiter and the orange giant Aldebaran lurking above.
For cosmic enthusiasts, January 2025 promises to bring additional excitement with the Quadrantid meteor shower expected to peak on the night of January 3, showering the sky with up to 200 meteors per hour.
While the allure of witnessing the 'Black Moon' may be marred by its invisibility, it presents significant opportunities for those willing to engage with the cosmos. Stargazers are encouraged to raise their eyes to the heavens and seize the moment to appreciate the beauty and mystery of the infinite universe as they usher in the New Year. The 'Black Moon', though hidden from view, marks another fascinating chapter in astronomical observation, seemingly reminding humanity of our enduring connection to the celestial bodies above.
