Circle of Stars

12/24/06 – 12/30/06

What a lovely time of year to see the stars. It’s always been said that winter stargazing is the best stargazing of all. The sky is dark right after dinner, and is lazy to get bright again the next morning, giving us the longest nights of the year. With our mild winter so far, it’s not such a task to spend a few minutes looking heaven-ward.

What’s up there to see? Looking south, you’ll see the “wreath” - seven stars that form a ring in the winter sky. Some call it the “winter circle.” It’s so sparkly bright, I like to think of it as a wreath of candles sparkling all night long. Four of these seven stars are in the top ten list of bright stars of all time.

Let’s start with the Bull’s eye. Though it’s only the 13th brightest in the sky, it’s a noticeable star. Aldebaran is the name of the pink-tinged eye of Taurus, the Bull. Since we’re starting our circle with this star, let’s be sure we know which one it is. Use the three stars of Orion’s belt, from east to west, to make an arrow that points up to it. It’s the top star of a V-shape of stars, outlining the face of Taurus. From there, you can look back at Orion’s foot, a bright blue-white star called Rigel, from the Arabic ar-rijl, “the foot.” That’s one hot foot! Rigel is much hotter than our own sun, and the 7th brightest in the sky. Now we are going clockwise around the circle, and the next stop is the most serious one of all. It’s Sirius, the number one brightest star in the whole night sky. Sirius is also nick-named “the dog star” due to its position as the wet, shiny nose of Canis Major, the big dog. Now we are east of Orion, and can look up from Sirius to another bright star in a dog constellation. This time it’s the little dog, Canis Minor. The star’s name is Procyon, which means “before the dog” referring to the fact that Procyon rises slightly before Sirius, the dog star. It’s the 8th brightest star in the sky.

We are halfway around, and the next two stars are the Twins. Castor and Pollux, the twin boys of the god Zeus disguised as a swan, and Leda. The two stars are inseparable, just as the twins were during their life, so the stories go. At the top of the circle is a bright star called Capella. It’s very high up in the sky, and it is the 6th brightest star in the sky. Its name means “she-goat.” It is part of a constellation named “Auriga” which sounds a little like Orion, who is just below him. Auriga is a Charioteer, but he is holding baby goats in his arms, known as “the kids.” They are a cute little triangle of faint stars near Capella, who must then be the Momma goat.

And then there’s the famous star Betelgeuse, though it lies more toward the middle of the circle. It is the 10th brightest star in the sky. As the shoulder (or more literally, “armpit”) of Orion, it shouldn’t be forgotten in our winter stargazing.

I hope you enjoy the embracing wreath of winter stars, as you enjoy the embraces of family and friends this holiday. Joy and peace to you all!

Until next week, my friends, enjoy the view.
