A Q&A and discussion happened after I gave my presentation at the Launceston Skeptics in the Pub (Episode 99). Listen in as we talk about the goals of skepticism, what other kinds of astronomy topics there are, and about real astronomy observations.

A mysterious crop circle appeared during the night of December 27-28, 2013, in Chualar, California. Security guards quickly came to guard the circle, and then it was mysteriously plowed under just a few days later. Crop circle researchers point to numerous lines of evidence that this was made by aliens, but it was later revealed to be a publicity stunt by NVIDIA. Or was it?

For the hundredth episode of the Exposing PseudoAstronomy podcast, I pay homage to paranormal radio programs and play the credulous host with two guests and several callers. The show is complete with commercials and bumper music and spans two nearly hour-long segments.

In July of 2012, I did an analysis of a photo purported to show a genuine ziggurat (a step pyramid) on the Moon. I showed that it was more likely to be a hoax than not. What ensued grew to more than I expected, with name-calling, mud-slinging, various side-claims, and other things that I relate in this live talk I gave twice while in Australia.

Michael Heiser is an expert in ancient languages and his work led him to investigate the possibility - or the claimed evidence for - ancient aliens and related materials. In this second part of a two-part series, we talk about the claims of Zecharia Sitchin; we don't discuss the specific details, but rather we delve into the claimed evidence that Sitchin used in his numerous books about the Anunnaki and Nibiru.

In this first part of a two-part series, we talk about how he got interested in the topic, his approach, and an investigation he facilitated into the infamous "MJ12" documents.

The Star of Bethlehem is perhaps one of the most famous astronomical events, but it's one that we're not even sure really happened. Much ink has been spilled on the topic, and in this interview, Aaron Adair talks about his new book (The Star of Bethlehem: A Skeptical View) and the methodic approach he takes, examining primary source material, interpretations of the text and possible events at the time, and what, based on the available evidence, the famous Star may have been, or if it was ever there.

Zecharia Sitchin's ideas about Planet X were discussed in Episode 23, where I also presented numerous reasons why his Planet X - Nibiru - does not exist. This episode discusses some of the news stories over the past decade that the man posted to his website and claimed supported his ideas, and I address whether they do or do not.

What a scientist means by "accuracy" and "precision" are usually different from common, every-day use. The process of formal error analysis and their propagation to a final formal uncertainty applied to a final result is also generally not well understood. This episode discusses all of these, focusing on different types of error in scientific data and experiments.
