Constellations aren't always made up entirely of stars

A constellation can be a combination of many different types of stars, each with a different story, and sometimes a spot in a constellation isn't even a star.

Take Orion for example ("lovely camera image" below
courtesy NASA). That red spot in the lower left, Orion's upper-right shoulder, is a red giant (near the end of it's lifespan), that may have consumed or spun-off planets that once harbored civilizations.

In the upper right (Orion's lower left foot) is supergiant Rigel, at the prime of life, possibly shining light on a thriving civilization at its peak.

Now check out the red spot in Orion's belt. It's not a star, but "the stellar nursery known as the Great Nebula of Orion."

About Me

My photo
I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
