US readers should be aware of Monster of the Milky Way, a PBS program on Nova that’s scheduled to air tomorrow evening. It’s about the search for supermassive black holes in the center of galaxies and ties in nicely with this morning’s post on galactic jets. Those of you with high-definition sets are in for a treat, though you may wind up taping it if the doorbell gets active enough on Halloween. The show runs at 8:00 Eastern time.
