    Amazing but I thought an atom would be smaller.

      It’s a picture of an atom re-emitting laser light which is what is visible by the naked eye. An actual atom is “visible” only under advanced electron microscopes

    This is so cool. Nature never ceases to amaze me.

    When illuminated by a laser of the right blue-violet colour the atom absorbs and re-emits light particles sufficiently quickly for an ordinary camera to capture it in a long exposure photograph.
