Over at 365DOA, I bring tales of early Pluto, the original controversy, and of things we can no longer discuss, for fear it will drive us mad.  Enjoy the podcast of Plutonomicon.  Pluto is no stranger to controversy. Let us ignore the current planet/no-planet nonsense and look at the heady early years of its discovery.  I found a monograph by a 1920s professor, who attempted to correlate some early ‘Planet X’ discoveries with Pluto. It being October, I thought a trip to the way-back machine would be useful in understanding just how unusual Pluto is, both now and when it was discovered.  Give it a Halloween-season listen!
