Is the Sagittarius constellation a teapot or an archer?

While some constellations demand our attention by the brilliance of their stars alone (Orion being the most noteworthy example), others are attractive because of their patterns of more modest stars. 

Often the pattern is quite unrelated to the official name of the constellation. Most of us find it quite impossible to put ourselves in the frame of mind of whatever ancient stargazer placed a centaur, or even a standing archer for the stars of Sagittarius. In his classic constellation guide, "The Stars — A New Way to See Them," the late Hans Augusto ("H.A.") Rey, did find a way to turn the stars of Sagittarius into a standing archer. 

Nevertheless, whenever I'm giving a star talk either outdoors or under the pretend universe of a planetarium dome, I take delight in pointing out that constellation's Teapot, a device not familiar in antiquity. 

Now prominent in September skies, and crossing the meridian as night falls, is the asterism that most modern stargazers recognize as the "Teapot in Sagittarius," which, quite possibly, is the most perfect of all the sky pictures we have. 

Just think: we happen to reside at just the right spot in our galaxy at just the right moment in time to witness a group of eight bright stars forming an excellent depiction of an object that is very familiar to us all. 

To the best of my knowledge, the person who most popularized the Teapot pattern was Henry Neely, who lectured at New York's Hayden Planetarium during the 1940's and '50's and who The New York Times referred to as "the dean of New York stargazers." One of Neely's acolytes, George Lovi, who designed the monthly star charts for Sky & Telescope magazine, later pointed out that some neighboring stars relative to the Teapot could also portray other requisites for a tea service. 

From several faint stars, poised above the Teapot's lid, Lovi formed the Teaspoon, ready to be used. And below the Teapot is a charming circlet of nine stars ranging from fourth to fifth magnitude, which was one of the 48 original constellations cataloged by Ptolemy in the second century AD: Corona Australis, the Southern Crown; a star pattern of considerable antiquity. It is said to represent a crown of laurel or olive leaves.

While it's small enough to be squeezed into the bowl of the Big Dipper, its distinctive pattern attracts attention as soon as one has a good look at that part of the sky. 

And Mr. Lovi turned it into a Lemon! 

Incidentally, if any of you prefer milk with your tea, you can readily convert the handle of the Teapot into a bowl, and the top of the pot (along with an adjacent star) into a bent handle, at one time, popularly known as the "Milk Dipper," which presumably can be used, to dip up the Milky Way.

Ostriches and Centaurs  

Sagittarius is one of the 12 constellations of the zodiac. Not knowing much about teapots, the ancient Arabs thought of the triangle that forms the spout as a group of ostriches on their way to drink from the Milky Way, and the quadrilateral of stars that formed the handle as ostriches returning from their refreshment. 

Sagittarius is generally thought to be a centaur — half man and half horse — and is usually considered to be Chiron, who is also identified with the constellation of Centaurus the Centaur. However, Sagittarius is seen as holding a drawn bow, which is not in character with Chiron, who was known for his wisdom and kindness. Some say that Chiron created the constellation to guide Jason and the Argonauts as they sailed on the great ship Argo. 

Starry wonderland  

This region in many ways might be the most remarkable in all the heavens. It is a veritable starry wonderland whether viewed with the unaided eye, with binoculars, through telescopes, or on photographs taken by great observatories. 

Here in the direction of the central region of our galaxy is the great Sagittarius star cloud, brightest and grandest of all the regions which form the framework of our home galaxy. Here the band of the Milky Way is at its broadest, although cut by dark bands of interstellar dust. It is a treasure trove of galactic and globular clusters, plus bright and dark nebulas.
