A return to a tried-and-true subject of skepticism: the Apollo Moon Hoax. In this shorter episode, I discuss two of the most common claims that you may hear: Why does the US flag appear to be waving in photographs, and if we went to the moon, why haven't we been back?

In 2006, the International Astronomical Union sparked an uproar and furious debate among scientists and non-scientists alike when they voted for a definition of the word, planet. Numerous proposals since that time have been made for the definition of that term. Eleven years later, a new proposal has gotten a lot of media attention and in this episode, we discuss that new proposed definition. This is closer to a friendly debate style because the host of this podcast and the guest have different points of view on this issue.

In past episodes, I have talked about how you can't get any more information out of an image than what is in a single pixel. Dr. Tod Lauer is an astronomer who has worked on all kinds of telscopes and instrument data and has developed numerous image processing techniques over his career. In this episode, we discuss some of those and how to correctly - versus incorrectly - apply them to image data to get to the best representation of the original object, or what the image was trying to capture.

In a special cross-over episode, the cast of The Reality Check (Cheque?) podcast come over and we all did short-ish segments on astronomy-related topics: Do we live in a black hole, the Drake equation, are aliens likely to be hostile, did Earth's magnetic field recently collapse, and lunacy. I also did a quiz and learned how difficult it is to make quiz questions that work over a podcast.

The scientific method is the process through which most modern science is done. Whether done explicitly in its formalized steps or not, it underlies the very basics of how we know what we know, why science is inherently a self-correcting process, and why when there exists a long-standing scientific consensus with broad support, it should not be taken as a political whim by a few motivated people.

Magic mirror on the wall, when will reality shifts affect us all? A phenomenon known as the Mandela Effect has been making the rounds of paranormal shows for the last year or so, and it seems silly until they start to use real science to back it up. Then, I get mad, and you don't want to see me get mad. In this episode, we learn about our changing knowledge about the structure of the Milky Way Galaxy.

Impact craters form the basis of, or fit into the claimed evidence for, several different kinds of pseudoscientific claims. In this episode, I review two of them and also discuss some sensational headlines and why those headlines were wrong.

Radiation is a mechanism for a large array of pseudosciences out there today, almost on par with quantum mechanics. The purpose of this episode is to provide a primer of radiation - what it is, what it isn't, why some is scary, and why some isn't. In going through this discussion, I also address numerous pseudosciences, including claims by proponents that the Apollo missions were hoaxed, that granite countertops are deadly, that microwave ovens are irradiating your food, and that cell phone and wifi signals are harming you in some way.

This podcast show most often focuses on refuting pseudoscience with real science, but it rarely sets out to make a positive case for real science. This episode is one of those rarer ones where I have used an unlikely source - youn-Earth creationists - to explain the case for why Earth is round and not flat.

Planet X is one of those topics that keeps coming up in pseudoscientific circles, in part because people who have been claiming it will come by and cause destruction continue to do so, making up new excuses as to why their last prediction failed. In this episode, I delve into the latest claims by Nancy Leider, one of the originators of the Planet X causes doom mythology, and I discuss some of the supposed discoveries and announcements in 2016 in the scientific community about a real extra, as-yet-unseen planet in our solar system.
