Well basically Google sky is one image.
Hardly. How would Google get a single image of the entire sky, the entire celestial sphere, without the sun, earth, or any planets visible in the
image? They wouldn't, not in a single image. Google sky is a mosaic of many, many images from a variety of all-sky surveys which themselves consist
of many, many images surveying the night sky with various telescopes. Most of the visible light images you see in the zoomed out view come from the
Digitized Sky Survey, which are digital scans of photographic plates from the Palomar Sky Survey and its southern hemisphere counterpart. It's very
important to keep this in mind, particularly if you plan to try to "find something" by "artifact hunting" in google sky. A serious researcher should
always look up the primary source material when it's available, instead of relying on secondary sources like google sky. Google didn't take any of
those images, they were taken by pre-existing sky surveys and then stitched together. What you're doing is zooming out beyond the 360 degrees of the
sky, so the mosaic simply gets tiled and repeated multiple times. Move your mouse cursor from left to right and notice how the right ascension
repeats when you zoom out too far.
