Discoveries using the telescopes on Mauna Kea

Thanks for the link, Paul. As to what I think, well, the theoretical evidence based on the orbits of some Kuiper Belt objects is pretty convincing that there is something relatively large out there. As Brown says in the 60 Minutes video, it's unusual for a scientist to say something is certain and if I were in his position I would be a little more cautious, but I think it's very likely the planet exists.
