What a difference a day makes...

During the course of a year, as the Earth orbits the Sun, the position and timing of the Sun set changes. Below are two photographs, taken exactly a day apart and then superimposed on one another, that illustrate just how much it changes!

Remember! Never look at the sun directly, and it can result in blindness.

  1. That is remarkable, to be able to see it visually, especially when you know the physics and figures behind the changes, it's just remarkable. Adds another level of fascination.

    Great picture!
