Well, YEAH! Google Earth/Moon/Mars/Sky/Omicron Persii 8 are
entirely created using image manipulation. Photos that are taken at different
times (in the case of Google Sky, decades apart) get stitched together to form an
approximation of the scene.
It makes a useful tool, but you must recognize its limitations:
- It is not real-time. I was amused that you heard about about a moving object and went to a Google scene to see it. That's like hearing about a
parade and going to Google Earth to see it. In at least one recent, similar thread, the sky view image was produced from a plate photographed in
1977.
- Image anomalies are unavoidable. Each of the above products are produced in similar ways - they take two-dimensional photos and stitch them
together to show a spherical object. All kinds of errors creep in. Sometimes two adjacent images are taken at different times
(
example), sometimes they are taken from different
angles (
example), and sometimes you get a bug in the
scanner (

celestial pole. Anyone familiar with maps knows that on 2D maps of spherical objects, distortion gets heaviest at the poles. There are different
ways of dealing with this, but they all have their ideosyncracies.
As such, they should be considered useful, but not necessarily "accurate".
