Carl Sagan attempts to detect cosmic rays in a lava tube. The Crab Nebula, the supernova which occured in 1054, is discussed. "Neutron star matter weighs about a mountain per teaspoonful." This video is from Carl Sagan's Cosmos episode 9, "The Lives of Stars."

  • A knife through warm butter? I think you're doing it wrong...

  • Every second they're penetrating me? They should've at least taken me to dinner first..

  • @cellovid Fuck those aliens, I want to see a supernova.

  • Is there so connection to the extended daylight found in the Alaskan area?

  • @bunkmasterflex David Bowie is special - as are you.

    In fact, you are extra special. Appreciate. . . . . in the dance . . . .

  • @goog2k Does that make David Bowie More or less special? just teasing

  • @cellovid or the Rigel superstar...

  • @rocke4444 It would happen as Carl described it. So kids, do not try this at home.

  • Runnnn dude

  • Carl Sagan said, "We are star stuff" and "a way for the cosmos to know itself."

    All the atoms on earth and in our bodies came from supernova that blew up over 5 billion years ago.

    Aren't we all just walking, talking stardust -- this cosmos become AWAKE and looking back at itself? -- and aren't we intimately connected to it all?

    We are this wonder called life become AWAKE. Please enjoy the dance.

    And ultimately, nothing separates us from others in this grand mystery. Please be kind.
