Dave and Nick are here for the mid-July show. We present part two of our Harry Potter-style intros (The Chamber of Anti-Science) with a special cameo appearance from The Bad Astronomer, Phil Plait. Nick finds out all about white dwarf stars and planets from Matt Burleigh and then stands in for Tim in Ask an Astronomer. We also have reviews from listeners and a preview of the next show featuring galaxy evolution and the Galaxy Zoo.
