Moon to Pass in Front of the Pleiades Star Cluster
Listen to the story
A notable astronomical phenomenon is set to grace the skies over Algeria on Wednesday night, according to local reports.
The event involves the Moon passing directly in front of the Pleiades, one of the most recognisable star clusters visible from Earth.
This kind of alignment is known as an occultation, a term describing the moment when one celestial body temporarily blocks another from view.
During the occultation, the Moon will briefly obscure the cluster before it emerges again later in the night.
Residents of Algeria are expected to be able to observe the phenomenon with the naked eye, without requiring specialised equipment such as telescopes.
The report notes that similar celestial activity will also be visible over Jordan, where two separate astronomical phenomena are expected on Wednesday and Thursday.
Both of the Jordanian events have been linked to Al-Wasm, a traditional seasonal period associated with the onset of cooler weather in the region.
While the summary does not detail the exact nature of the Jordanian phenomena, their timing has coincided with this seasonal marker, drawing attention from local observers.
Astronomical occultations involving the Moon and prominent star clusters are relatively uncommon, which has generated interest among amateur skywatchers across the region.
The Pleiades, sometimes referred to informally in various cultures, is one of the closest and brightest star clusters to Earth, making it a frequent subject of public interest during such events.
Experts generally advise observers seeking a clear view of such phenomena to find locations away from heavy light pollution, where the night sky is darker.
The coverage of these events reflects a broader public interest in accessible astronomical occurrences that do not require professional instruments to appreciate.
No further technical details, such as exact timing or duration of the occultation, were provided in the original report.
Authorities and astronomy enthusiasts in both Algeria and Jordan are expected to share further guidance as the events approach.
