There’s a spectacular constellation in easy view this time of year – Orion, the hunter. Look due south (toward the downtown area) and you will see him, striding over the trees.

Orion was a minor Greek god and there are various Greek myths explaining why he is up there. In one, after a checkered history, he went hunting with Artemis and boasted he could kill anything on earth, whereupon Mother Earth killed him, possibly with a scorpion. Other goddesses persuaded Zeus to put him in heaven.
Use your imagination to make out the Orion’s body. The first stars you will notice are the brightest ones – reddish Betelgeuse on his right shoulder and bluish Rigel marking his left foot. They are both super-giants, hundreds of light years away, and two of the ten brightest stars that we can see year-round.
Orion’s “belt” is easy to see – it consists of three stars in a slanting row. In South America they are known as “The Three Marys “(Las Tres Marias). The Chinese call the constellation “Shen,” which refers to the three stars.
In western culture, the three stars in the belt are called Mintaka (900 light years away), Alnilam (4 million years old, 1,359 light years away), and Alnitak (800 light years away). All these are Arabic names that have come down to us from the period around 800-1200 A.D., when the Abbasid caliphate ruled the Middle East and the major astronomers in the world were in Baghdad and Damascus.
Hanging from the “belt” is a “sword,” which contains the famous Orion Nebula. You can see it in detail with ordinary binoculars. Because it is relatively close, this nebula is a favorite study of astronomers.
A long human history
People were looking at this group of stars and making stories several thousand years before Christ. In western history, the early Sumerians in Mesopotamia interpreted these stars as a man and called him their hero Gilgamesh. The Egyptians saw the constellation as Osiris, their sun god of rebirth. Orion is the ancient Greek name, and he is mentioned by that name in the Odyssey, the Aeneid and the Old Testament.
Many other peoples named this set of stars. For example, the Rig Veda (Hindu) calls them “Mriga,” the deer, and sees a group of stars in this part of the sky as a deer with hunting dogs. On our continent, the Lakota Indians saw a bison.
A sense of wonder
When I look at Orion, I remind myself of the many years the light of those stars has traveled to reach us. The vastness of space is hard to comprehend.
And, I enjoy imagining all the people who have looked at those stars and made patterns and stories about them.
I have found Wikipedia a good place to start – it has several articles on Orion, the constellation and its mythology. There are a number of commercial sites on the web if you search “astronomy.” Google Images has lots of pictures. And there are apps with star maps and info, such as Star Chart for Apple and Android phones and tablets.
