Neutrinos that have escaped from the hottest cauldrons in the cosmos are being captured in 18 000‐year‐old ice.
A neutrino telescope buried, under a mile of ice at the South Pole has been recording the interception of very high energy neutrinos (typically electron volts, or 1 TeV) for two years now. The AMANDA (Antarctic Muon And Neutrino Detector Array) collaboration has begun reporting its first results at meetings in recent weeks. A preliminary pass through the first four months of data harvested in 1997 has already yielded about 20 unambiguous neutrino events. So one can expect AMANDA, in its present configuration, to yield about 100 events per year above its neutrino‐energy threshold of roughly 50 GeV
