Phil Plait will be calling into Desert Bus at 11am PST on Saturday, November 15th.

Phil Plait, PhD, is an American astronomer and the mind behind the science blog Bad Astronomy. While the blog has an astronomy focus, Phil also writes about skepticism, pseudoscience, and antiscience topics. This blog was hosted by Discover Magazine, near the end of 2012 it changed hosts to Slate Magazine.

He is the author of, “Bad Astronomy: Misconceptions and Misuses Revealed, from Astrology to the Moon Landing “Hoax”“, which covers debunking astronomy-related urban legends, and “Death from the Skies!: These are the Ways the World Will End“, describing ways astronomical events could wipe out all life on Earth.

It was announced in early November that Phil is set to become a host for a new astronomy series on the Crash Course Youtube channel. This series will also be distributed through PBS’s Youtube network and into classrooms through PBS LearningMedia.

There’s also an asteroid named after him.
