Remember the old children's song, "I'm a little teapot, short and stout, here is my handle and here is my spout?"

Well one of the classic constellations in the summer sky is Sagittarius, and it really does look like a quaint little teapot in the low southern sky after evening twilight.

You can easily find the handle on the left and the spout on the right. It even appears to be pouring its celestial brew on the tail of Scorpio, the Scorpion, its neighbor to the west.

Now if you are a mythological purist, which isn't all bad, the constellation Sagittarius is a centaur shooting a bow and arrow. A centaur is a creature with a human head and the rear, tail and legs of a horse.

In my time I've known some people who were horse's rears, but that's another story.

Lots of luck seeing Sagittarius as a centaur with a bow and arrow. You're much better off looking for the little teapot.

Not only is Sagittarius the teapot a cute little constellation, it's in a very important part of the sky. It lies in the foreground of the center of our Milky Way Galaxy.

All of the stars we see in our part of the Milky Way, which at last count may number more than 500 billion, form the shape of a giant spiral 100,000 light years across.

When we see that bright collective glow of stars in the dark summer skies running from north to south, we are looking edgewise into our galaxy.

The glow around Sagittarius may be a little brighter because it's located in the general direction of the Milky Way's center. That glow would be almost as bright as a full moon, but there's a lot of dark interstellar clouds and dust that block the heart of our galaxy from our view.

It's well worth it to scan around Sagittarius the teapot with binoculars or a small telescope. There are all kinds of neat star clusters and nebulae you can see.

In fact, just above the spout of the teapot you can see the famous Lagoon nebulae with the naked eye, if it's dark enough.

In that bright hydrogen gas cloud 4,500 light years away, new stars are constantly being born. By the way, one light year equals about 6 trillion miles!
