SUMMARY: A new telescope lodged in the ice of Antarctica has completed the first map of the high-energy neutrino sky. AMANDA II consists of 677 glass detectors in the shape of a cylinder sunk into the Antarctic ice at a depth greater than 500 metres. It actually looks down, through the entire Earth to view the Northern sky for neutrinos, which move at high velocity and pass through almost all matter unhindered. AMANDA II has discovered neutrinos with 100 times the energy of any produced in laboratory experiments on Earth.
