    This laser was fired from a mountain top in Chile, aimed at the center of the Milky Way galaxy to study the atmospheric distortion of astronomical lenses. It was featured on NASA’s “astronomy picture of the day” website July 31, 2007.

    Given the diameter of the Milky Way is 100,000 light years and our Solar System is located approximately 3/4ths of the length of the spiral arm from the galactic center, it will take this laser approximately 37,500 years to reach the center!

    Kind of mindboggling!

    Sorry about that…. When I follow Ron’s instruction about adding a picture, the pop up window is just code. I’m using a Macbook, Ron if your out there, do the rules apply for a mac.
