this is kind of like a Planet Earth about the universe. this one was awesome, it got into just how ridiculous the sun is. it showed all kinds of footage of solar flares and CME's, and showed just how dangerous they are to the earth. they tried to relate the energy output to terms we could understand, and they are just unfathomable. the sun puts out 380 billion billion megawatts of power. yes, billion billion. i believe the next episode is about Mars.
there was an equally informative show relating to this topic called "The Death of the Sun". that was interesting. i keep missing the Universe specials though.
