Night Sky Photography -- 07-20-2025 -- Luna Occultation Of The Pleiades Star Cluster



Early this morning, about an hour before sunrise here in South Carolina, I set up my camera and tripod and captured these outstanding shots of the Waning Crescent Moon with Venus rising in the eastern sky just 45 minutes ahead of the Sun.

The first photo is a really beautiful shot of Luna overhead with bright, beautiful Venus between the branches of the trees. Venus is currently inside the Constellation Taurus The Bull.

The planet Uranus is also currently close to Luna in the moon's orbit as seen from here on the Earth. Uranus is too far away to be visible in the shot -- about 1.86 billion miles (or 3 billion kilometers, or 19 astronomical units (AU) away -- but I labeled the current location of the 7th planet of our Solar System where it could be seen with a good telescope.



When I downloaded the photos to edit and label them, I noticed that I'd also captured the bright star Aldebaran -- the Eye of the Bull -- clearly visible through the leaves of the trees. In my second photo I captured a close-up of Venus and saw that Aldebaran was visible in that one as well.



The main event, the reason that I was up so early, was to capture the moon as it passed in front of the Pleiades Star Cluster (or "Seven Sisters") in its orbit around the Earth. I perfectly captured the moment when Luna was almost dead center in its occulation with the Seven Sisters catching all of the major stars of the cluster, except for Maia which is hidden by the moon. 



Finally, this morning at around 10 a.m. EDT Luna reached perigee -- the moon's closest point to Earth in its elliptical orbit -- at approximately 228,690 miles (or 368,041 km) away.

Tomorrow at about the same time, Luna will move lower towards the east and the sunrise between Venus and Aldebaran in the morning sky. If clear skies permit I will try and capture a good photo of that celestial event as well. Till then keep your eyes to the skies, y'all!
