Bad Astronomy

Bad Astronomy: Misconceptions and Misuses Revealed, from Astrology to the Moon Landing "Hoax" is a non-fiction book by the American astronomer Phil Plait, also known as "the Bad Astronomer". The book was published in 2002 and deals with various misunderstandings about space and astronomy, such as sounds being audible in space (a misconception because in the vacuum of space, sound has no medium in which to propagate).

Plait's first book received generally favorable reviews within the academic and astronomy communities and was the first volume in the Bad Science series by John Wiley & Sons Publishing.

Overview

Inspired by the author's web site, "Bad Astronomy," the book attempts to explore twenty-four common astronomical fallacies and explain the scientific consensus concerning these topics within the field of astronomy.

The book explains and corrects many ideas relating to space that, according to Plait, are mistaken but nevertheless often portrayed in popular movies. Plait also dedicates much of the book to debunking the idea of a Moon landing hoax and explains why astrology should not be taken seriously. A part of the book describes the Moon's tidal effects and explains the Coriolis effect, why the sky is blue, the Big Bang and other related topics.
