#8 – Stars don't move across the sky
All celestial bodies move, even the stars. Because of the vast distances between the stars, it is hardly to see the significant changes over the human life. Only with the help of accurate measurements, scientists can discover how the stars move. Such difference can be noticeable with the naked eye only after thousands of years. Only a small number of stars moving so fast that it can be shown in the photo. The most famous example is Barnard's Star.
