<p>This could shed some light (no pun intended) on the matter. Yesterday, in an article entitled, "Paczynski wins astronomical society's highest honor", it was stated:</p>
<p>"Princeton astrophysicist Bohdan Paczynski has been awarded the American Astronomical Society's highest honor, the Henry Norris Russell Lectureship, in recognition of "a lifetime of eminence in astronomical research."</p>
<p>With regard to planet discovery, the article stated:</p>
<p>"Paczynski, the Lyman Spitzer Professor of Theoretical Astrophysics, pioneered a technique known as gravitational microlensing, which recently enabled researchers to discover the smallest planet found outside of our solar system." </p>
<p>In addition to his cofounding the Optical Gravitational Lensing Experiment (OGLE), I do not think we can call his contribution to the planet's discovery anything but large.</p>
