IceCube Construction Featured on National Geographic Channel

According to my Librarian, The National Geographic Channel will be re-airing a show on man made marvels tomorrow and next Thursday on antarctic construction, with a partial highlight of the IceCube Experiment.  IceCube is a cubic kilometer of arctic ice laden with photomultipliers, and a surface array to detect air showers.   The PMT’s pick up Cherenkov light from fast moving charged particles (mostly muons), which come from cosmic rays and neutrino collisions with the water molecules.  Once completed, you can think of IceCube as being, among other things, a giant cubic telescope that views the universe with neutrinos instead of light.  It also contains an earlier detector called AMANDA, which is shown here as the yellow cylinder.  Photo comes from  gallery.icecube.wisc.edu.
