In the Bad Astronomy introduction, Phil Plait says, "As an astronomer, teacher, lecturer and all-around science junkie, I am exposed to all sorts of people and their ideas about what goes on in the sky around them. I have been delighted to find that most people are very curious about the night (and day!) sky, but unfortunately a lot of misinformation is spread about astronomy. Sometimes this information is just plain silly, but many times it makes just enough sense that people believe it." And boy, what some people believe! But, Phil takes time to poke holes in a lot of fallacy balloons: the face on Mars? Check! The faked moon landings? Yepper! Bad science in 'science' fiction movies? Got it! He also spends a lot of time talking about real astronomy in his blog. If you have any interest in what's going on over your head or the crazy stuff that people think is going on over your head, you need to make Bad Astronomy a regular stop.
