IceCube Neutrinos Point to Long-Sought Cosmic Ray Accelerator

In two papers published today in Science, IceCube together with partner telescopes and observatories on Earth and in space announced the identification of blazar TXS 0506+056 as the first likely source of high-energy neutrinos and cosmic rays.


The hardest search yet: cosmogenic neutrinos

Billions of years ago, an ultra-high-energy cosmic ray––maybe a proton––escaped the environment of a powerful, extragalactic source.


Artist Tim Otto Roth synthesizes IceCube

When artists and scientists meet, anything can happen. Tim Otto Roth met Christian Spiering, former spokesperson of the IceCube Collaboration, in Zeuthen. Tim was at DESY to present "Cosmic Revelations," an installation which resembles the KASCADE cosmic ray detector in Karlsruhe. And as soon as IceCube was mentioned in a conversation between the two of them, they were hankering to work on a neutrino installation..


Week 37 at the Pole

Just because the sun’s coming up, doesn’t mean it’s getting warmer yet. In fact, they’ve had some tremendously cold days at the Pole, with the thermometer hitting –100 F last week.
