The data revealing the Sept. 22, 2017, neutrino detection
This is a high-energy neutrino detected by IceCube on Sept. 22, 2017. With an estimated energy of 290 TeV, this was the 10th alert of this type sent by IceCube to the international astronomy community and launched a series of multi-messenger observations that allowed the identification of the first source of high-energy neutrinos and cosmic rays.
The neutrino event display shows a muon, created by the interaction of a neutrino with the ice very close to IceCube, which leaves a track of light while crossing the detector. In this display, the light collected by each sensor is shown with a colored sphere. The color gradient, from red to green/blue, shows the time sequence.
