High in the northern sky this evening there is a somewhat obscure constellation called Auriga, the Charioteer, in legend and myth, an early king of Athens, the son of the blacksmith god Hephaestus or Vulcan, and the inventor of the chariot. Another story portrays him as Phaeton, whose father was the sun god Helios, and who drove the solar chariot on a reckless path across the sky. Now if you're good at imagining constellation shapes, you'll immediately see Auriga in all his glory - a man, driving a chariot, while holding on to a whip in one hand, and a bunch of small goats in the other. But if you have that kind of imagination, then I probably didn't have to tell you all that. For the rest of us, Auriga looks like a pentagon shape - a five-sided figure of stars, marked by a bright yellow star - Capella, the head of the charioteer. Look for the goat kids also, a few tiny bright stars just to the south of Capella.
