The reboot of Cosmos (available on Hulu if you're into two minutes of ads every ten minutes) is fairly good pop science. They're hosted by Neil deGrasse Tyson.

Pros: The show makes me happy-cry on a regular basis. There's a clip in the opening sequence where a dandelion seed floating in the wind fades in to Voyager. The show is pretty heavily against religious tomfoolery, death, and staying on Earth until the civilization collapses and/or destroys itself.

Cons: The show owes a lot of its goodness to Sagan. NGT is leaning really heavily on his Crowning Moment of Awesome with Sagan before NGT went to undergrad. The CG is atrocious when it's not based on Hubble pictures. The anti-religion bits are heavy-handed to the point of being outright trolling (which one might argue was also a feature of the original).
