A rare astronomical phenomenon is reportedly occurring in Mecca, where a celestial body aligns vertically over the Kaaba [1, 2].
This event is significant because the vertical alignment causes light to fall directly on the structure, resulting in the temporary disappearance of shadows. Such occurrences are often viewed with spiritual and scientific interest in Saudi Arabia.
Reports regarding the specific celestial body involved are contradictory. Al Jazeera Arabic said the event was the sun aligning with the Kaaba [1]. However, a report from MSN said that the planet Jupiter was the body aligning over the site [2].
There are also conflicting accounts regarding the timing of the event. Al Jazeera Arabic linked the phenomenon to a day of Eid, though it did not provide a specific date [1]. In contrast, MSN said that the event took place at dawn on Friday, Dec. 5, 2025 [2].
The mechanism behind the event occurs when the path of the sun or a planet passes over the latitude of Mecca [1, 2]. This positioning ensures the light is perpendicular to the Kaaba, eliminating visible shadows on the ground.
According to Al Jazeera Arabic, this specific astronomical alignment is a rare event that occurs every 100 years [1].
Local observers and astronomical groups, including the Jeddah Astronomy Society, have monitored these patterns to determine the exact moments of alignment [2].

The discrepancy between reports regarding whether the sun or Jupiter caused the alignment—and the conflicting dates—suggests a lack of consensus among reporting sources. While solar alignments at specific latitudes are documented astronomical events, the claim of a centennial cycle and the involvement of Jupiter would require further verification from international astronomical bodies to confirm the scientific validity of the timeline.
