Check out Carnival of Space #38 over at Sorting Out Science. The detective story format is a little unconventional, but you'll find numerous clues to the subjects of the blog posts sprinkled through the text (plus there's that handy mouse-hover thing that shows you the link itself down at the bottom of your browser window).
P.S. The "Dirk Galaxy - Space Detective" logo has nothing to do with the carnival (which features Shorty Barlow, private eye), or with space for that matter, it was just the result of a Google image search. But I listened to the latest (2003) episode and it had some amusing moments, especially if you like Maxwell Smart impressions.
