Even cooler: my own TED talk, "How to Defend Earth from Asteroids" is one of their initial offerings! They packaged a few space talks, including mine, along with talks by Brian Cox, Carolyn Porco (that one is a must-see), Jill Tarter, and many others. There are also packages about health, biology, computers, and more.
If you are a Netflix subscriber these talks are free. I'll note they're all online at the TED site as well, but this may open up the talks to a bigger audience, which I think is just fine. I have Netflix, and found them easily by searching on "TED" (duh).
Not only that, but TED has a new initiative for education called TED-Ed: Lessons Worth Sharing. These are short, great educational lessons that fit well inside established classroom curricula. There are lots of such things available, of course, but these are hand-picked and will augment a teacher's lessons. I think this is a cool idea, since TED already has a trusted brand and a wide audience. Just to be clear, there lessons are online, not on Netflix like the big talks.
If you don't have Netflix, well, like I said you can find these talks on the TED website. And because why not, here's mine. Enjoy:
