Walkabout the Galaxy

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.
