The Constellation Auriga
We now will follow the two stars across the top of the cup of the
and cruise westward to the star Capella in the constellation Auriga.
Auriga is often shown seated and holding a young goat in his arms, represented by the small thin triangle of stars along the right side of the pentangle. These stars are known as "The Kids". The star at the tip of this triangle is e (epsilon) Aurigae. This is one of the brightest stars in our galaxy, a huge star 2,000 light years away which, every 27 years, is eclipsed by something even huger -- eclipsed for two full years. What it is that blocks this star is a deep mystery.
Auriga lies right across the Milky Way and therefore contains lots of interesting stars and star clusters. Someone want to tell me what that means -- "The Milky Way"? Where is the Milky Way (someone will always point it out). Most people recognize the Milky Way as a band of light across the night sky, but what is that band of light - where does it come from?
Well it's a bit like looking at a gravel road. Close to you, you can see individual stones, while off in the distance the road merges into a uniform gray. When you look at the Milky Way you are looking at the disk of our galaxy from the inside - the nearby stars you can see individually (most are less than 1,000 light years away), the distant stars merge into a hazy glow. So when you see that band across the sky you are really looking way off into the distance, into the "billions and billions" of stars that make up the disk of our galaxy.
You'll see a similar phenomenon when we look at the more distant galactic clusters. Through binoculars you see them as a hazy patch. When you see them through a telescope - that is, closer up - you can pick out individual stars. The better the telescope, the 'closer' you can get to the cluster, the more stars you can see.
