A while back when Jorge still trolled these halls we all had an extended discussion with him about the validity of the claim that we were discovering exo-planets orbiting stars. Over time he gradually ceded these were probably planets after all, but at the core of much of his early argumentation was something akin to 'seeing is believing' in that he mocked the reliability of the indirect methods being used to tease the planets out. Radial velocity and transit where key methods of the Early discoveries.
Here is a link to a timelapse 'video' of 4 planets orbiting their host star about 130 light years from here. Keep in mind the observed motions took place back a little before Edwin Hubble was born (the discoverer of the red-shift/distance correlation for galaxies and the pioneer in the use of Cepheid Variables as a distance scale, providing one of the first estimates of the Andromeda Galaxy's distance)
