Description
Planet 9, also known as Egotron in honor of its supporters, has never been seen. A new statistical analysis of a deep sky survey suggests that's because it doesn't exist. The object's existence has been proposed to explain an apparent clustering of the orbits of some objects that have the charming quality of actually having been directly observed. The astroquarks discuss the arguments for Egotron and how statistics and observation bias play into all this. Speaking of statistics and planets, Kepler's list of planet candidates keeps growing. Hear about the latest discoveries, nerd news, space trivia and more on this episode of Walkabout the Galaxy.

Tycho Brahe
On December 29, 1566, my knave of a cousin cruelly hacked my nose with a lucky strike, but I did not let that stop me from exploring the cosmos with my unparalleled observatory at Uraniborg. I did not need telescopes to revolutionize our understanding of the solar system. But I forgive you newcomers, using your machines to peer deeper into the sky. You cannot match my ingenuity and cleverness to transform the world with the naked eye. Continue on your Walkabout the galaxy, you are indeed standing on the shoulders of giants, or giant rather, me.
