Scientists have unveiled the first glimpse of the sky by a telescope that detects high-energy neutrinos. By spotting extremely energized neutrinos that emerge from the universe's most violent events, such as collisions between black holes, the new telescope is expected to provide unprecedented insights into such distant phenomena. It can also view high-energy subatomic particles that come from cosmic-ray collisions with atoms in Earth's atmosphere.
The telescope is the Arctic Muon and Neutrino Detector Array II (AMANDA II)--a collection of hundreds of sensitive photodetectors sunk deep into the South Pole ice (SN: 3/27/99, p. 207). After high-energy neutrinos ...
