The particularly cool bit about Scorpio is that bright star in the center. Antares. I think of it as Scorpio's heart for two reasons. One, it's bright red, a red super-giant star. Two, it actually beats, albeit much slower than a human heart, because it is a variable star, pulsing brighter and dimmer every 4.75 years.
Antares means "rival of Mars", because of it's red color. The Arabian name is much cooler: Kelbalacrab. It means "the scorpion's heart."
One more bit of Scorpio lore. The reason Scorpio and Orion are on opposite ends of the sky is because Gaia, the Earth Goddess, sent Scorpius to sting Orion, because he bragged about sleeping with her. Orion runs into the sea to escape, and dies there, but Apollo feels bad about the whole deal and hangs him back up in the sky, where he is put on the the opposite side as Scorpio, to keep them apart. So, as the sky revolves, he is forever running away from the deadly scorpion.
