In a previous post, November 2, 2012, I had realized, after several years of usage, that my astronomy book for telescopes, had showed our galaxy. The thing that struck me first was that the Earth we live on, was not shown. Yet, it was located around our sun in a very small section of one open spiral [See below, where the arrows located our Sun; one galactic view photographed from above and the other as a side view]. 
|The Upper register is our Summer view of the Via Lacta|
while the Lower register is our Winter view.
|The Earth in Orbit, 180° during the Fall and Winter|
And 180° during the Spring and Summer months..
This time, however, I remembered that Seven Macaw and Tlaltecuhtli have similar stories. Both have the color blue, and also have lost parts of their bodies: Seven Macaw, his teeth and metallic eye ornaments while Tlaltecuhtli lost her arms and legs to two different comets. All were then carried down to earth.
Remembering the information given my by my dentists; that all constellations are upside-down south of the equator, a thought struck me suddenly. What if there is only ONE Milky Way branch that we see, that within our single spiral?
However, having previously discovered that some constellations have only a 90° turn, while others have a 180° turnabout,both under AND over the equator, can it remotely possible that the view of the stars changed as different star formations, creating completely new constellations, even though they still retain their original shapes, with added stars making the newer southern versions?
I think that if astronomers created a huge cube as they have for the space shuttles to follow, and did a 3-D turn-around, one might just be able to distinguish the old as the cube is turning, just long enough to identify the new southern view. Are any astronomers able to do this project? I would like to know and probably a lot of other people would like to know something as rare as this also.
