One rarely sees earth and moon to scale at the correct distance. I think this leads many of us to often have a broken intuition about these things. And while these new images are spectacular, the distance between moon and earth is not obvious here. Look at e.g. [1]. It becomes immediately obvious why the shadow of the moon will only hit the earth rarely (during an eclipse). If it's not obvious, try holding two real objects at the correct scale / distance in your hands and make one throw a shadow on the other.

At scale, if the earth was the size of a basketball and the moon the size of a baseball, they would be about 7.5m apart.
