Orion, the Hunter, is by far the most famous seasonal constellation. No other is more distinguishable or bright as this northern winter constellation. The famous Orion's Belt makes the hunter easy to find in the night sky.
Orion looks very much like a person. First, you should spot Orion's Belt, which is made of three bright stars in a straight line. One of Orion's legs is represented by the intensely bright star called Rigel, one of the brightest stars in the night sky. His two shoulders are made of the stars Bellatrix and Betelgeuse. Betelgeuse is so luminant, that you can see its reddish color without a telescope. Other bright stars make up the two arms, one which holds a shield, and another that carries a club.
Many different civilizations saw this constellation in the sky. The most famous stories come from Greek and Roman myths. Orion was a famed hunter, and in one story boasted that no creature could kill him. Hera then sent a scorpion to sting the hunter. Orion smashed the animal with his club, but not before he was fatally poisoned. Both are now on opposite sides of the sky. They cannot be seen at the same time.
A different story tells of the love between Orion and the goddess, Artemis. One day, Orion was swimming out in the sea. Apollo, who very much disliked the man, bet his sister that she couldn't hit the object in the sea with her bow. Artemis didn't realize it was her lover, and shot Orion with an arrow. When she later found out what she had done, she honored the hunter by putting him in the sky.
Other myths come from Egypt and India. The ancient Egyptians believed the stars represented the god Osiris. Ancient Indian mythology says the constellation was called Prajapati. One day, Prajapati was chasing after one of his daughters. The star Sirius was angered by this, and shot an arrow at the lord. The arrow pierced his waist and remains as his belt.
There are several clusters and nebulae to view in this awesome constellation. NGC 2169 is an open cluster located half way up the arm from Betelgeuse. Next door is NGC 2194, a cluster containing about 100 stars. The famous Orion Nebula is located in Orion's sword, which hangs from the belt. It is so bright, that even the naked eye can see the fuzzy patch. It looks spectacular even with a small telescope or binoculars. Another nebula, the Horsehead Nebula, is located right below the belt. Unfortunately, it is too dark to see unless you are looking at a long-exposure photograph. There are numerous other objects in Orion, so scan the constellation with a telescope or binoculars on a clear night!
