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."



If you have never seen Cosmos, I strongly recommend it. It's full of great stories like this one. It is available on DVD, in 7 subtitle languages. Purchase links are below.
