The Full Moon Dances with the Seven Sisters

North America, 8:00pm

November 25th, 2015

The Moon turns full in the constellation of Taurus, the Bull, on November 25th. As always, a full Moon is not a good time for astronomy as the moonlight brightens the sky and washes out the fainter stars. Despite this, try looking for the Pleiades star cluster, also known as the Seven Sisters.

This famous cluster normally appears as a tiny group of stars on any clear night. They’re even visible from the light polluted skies of the city. But with the Moon close by, they’ll prove to be a challenge to spot with just your eyes. In the image, the Seven Sisters are the little blue white stars above the Moon. If you can’t see them with just your eyes, maybe you can see them with binoculars?

On a side note, I haven’t been posting much recently. The reason is twofold; firstly, with Venus, Mars and Jupiter clustered together in the morning sky and Mercury and Saturn too close to the Sun, there hasn’t been much to highlight this month.

Secondly, I’ve spent the past week finishing my new book, Easy Things to See With a Small Telescope. I’m currently awaiting the proof copy and the paperback and eBook should be available on Amazon from December 1st. Stay tuned for more details!

  1. I,ve been observing in Orion lately and I could predict the event you describe. As you say, thev full moon is not a great time for visual astronomy.
