At Long Last: IceCube Spots 28 High-Energy Neutrinos 109
Wired reports that IceCube, the detection facility built just to detect such things, has seen just what it was looking for, even though the researchers involved didn't know it at the time. High-energy neutrinos, the target that IceCube was seeking, weren't showing up as had been hoped, but it turns out that there were quite a few (nearly 30 already, with 2013's data still being recorded) in the three years that the detector has been operating — they just weren't obvious until the data was combed for it. "Most of the 28 high-energy neutrinos so far detected originate from parts of the night sky that don’t include the Milky Way, making it quite likely that they are arriving from a distant source. There are still too few neutrinos to make any specific conclusions about AGNs or gamma-ray bursts, but the IceCube team will continue gathering new data."
