Orion /ori-on/ [2 sylls.] as a boys' name is pronounced oh-RYE-on. It is of Greek origin. Greek mythology: Orion was a mighty hunter, the son of Poseidon, who was turned into a constellation. The Orion constellation contains three of the most conspicuous stars in the nighttime sky.
At the center is a pulsar (the remnant of the original star). This represents the death stage of a star's life (even though there is a pulsar left behind). The Orion Nebula is a cloud of dust and gas that is a star forming region. It is home to many protostars, and thus represents the early stages of stellar life. The Ring Nebula is a planetary nebula, which occurs as a red giant cools, throws off its outer shell and becomes a white dwarf.
