Jeddah, December 29, 2024 – Tonight, the skies over the Arab world will witness the rise of the last quarter moon in the Islamic month of Jumada Al-Akhirah, marking a significant phase in the lunar cycle. The moon will reach the last quarter at precisely 01:18 AM Makkah time, completing three-quarters of its orbit around the Earth. This event, which will remain visible for the rest of the night, provides an excellent opportunity for sky watchers and astronomy enthusiasts to observe the moon's surface in greater detail.
Eng. Majed Abu Zahra, the President of the Jeddah Astronomy Society, explained that during the last quarter phase, half of the moon’s surface is illuminated by the sun, while the other half remains in shadow. This contrast creates an ideal setting for observing the moon's intricate features, including its mountains, craters, and other geological structures. Abu Zahra noted that the "terminator" – the line separating the illuminated and dark sides of the moon – is particularly striking during this phase, as the interplay of light and shadow highlights the moon’s topography in a way that gives it a stunning three-dimensional appearance. He added that this phase offers an excellent opportunity for astrophotography, as the shifting shadows make the lunar surface more defined and visually captivating.
As the days progress, the moon will gradually move closer to the sun, transitioning into the waning crescent phase. In this phase, the moon will be visible briefly before sunrise, offering a fleeting glimpse of its shape as it prepares to enter the conjunction phase. This marks the end of the current lunar cycle and the beginning of the month of Rajab, one of the sacred months in the Islamic calendar.
The last quarter moon in Jumada Al-Akhirah is a moment to appreciate not only the beauty and science of lunar observation but also the cultural and spiritual significance it holds for many in the Arab world and beyond. For astronomers and casual stargazers alike, it is a reminder of the celestial rhythms that govern our universe and the wonders that unfold above us each month.
