Orion

The constellation Orion is a hunter. He is really easy to find in the sky! Look for the three bright stars that make up his belt. From there, you can find one of his legs, which is the star Rigel. One of his shoulders is the red star Betelgeuse. You should also find a shield in one hand, and a club in the other. Have you seen Orion in the sky before?

There are many myths about Orion. In Greek mythology, Orion was a great hunter. He thought that no animal could hurt him. So Hera sent a scorpion to sting Orion. Orion smashed it with his club, but not before he was poisoned. They are both in the night sky, but you can never see them at the same time.

A really famous nebula called the Orion Nebula is in this constellation. Look for the shape of a sword hanging from Orion's belt. If you see a fuzzy patch of light, that's the Nebula! Use a telescope or binoculars to see some cool colors inside it!
