NOVA: "THE PLANETS: JUPITER"
PBS, 9:00 p.m. ET
This new edition of Nova comes midway through Season 46 of this PBS science show’s long history, and it looks at the long, long history of Jupiter itself. How, why and when did it get to be the largest planetary body in our solar system? And what role did it play in forming the planets around it – and, maybe, in killing Earth’s dinosaurs? It’s not exactly a smoking gun, but Nova, in addressing that last question, presents what may be a smoking asteroid. Check local listings.
