Bad Astronomy

Bad Astronomy

The Bad Astronomy blog is all about real-world science — it covers the entire Universe, from subatomic particles to the Big Bang itself. Astronomy, space exploration, the effect of politics on science... you'll find it all here, as well as anything else that pops into the science-drenched brain of Phil Plait - astronomer, author and communicator. And you'll find it described with obvious joy and love for all things cosmic.
