A neutrino, for those of us who might not immerse ourselves regularly in the world of very small things, is a nearly massless sub-atomic particle that travels at just about the speed of light. Born in the cauldron of exploding stars, they can move through lead like you and I move through air. Hence, their nickname: "ghost particles." IceCube, a particle detector planted in the barren wilds of the South Pole, measures neutrinos in hopes to contribute to the scientific understanding of dark matter and other universal mysteries. From the homepage, have a look at About Us, which explains IceCube and includes interviews with drillers, scientists, and support staff. Check out the Science section to read All About Neutrinos and other linked articles.
