He’s back!!! Our pal Phil Plait the Bad Astronomer is back again on the Discovery Channel with the second episode of his new series, “Bad Universe.” It is on TONIGHT (October 6), so check your local listings here, and you can also find when it will be replayed in case you miss it. Above is a teaser/trailer of the second episode where Phil flies in an F-16 — it’s awesome! Just how much punishment can Phil’s frail, pale, scientist body take? Find out!
