On 12 February, a live stream from three locations (Amsterdam, Rome and Paris) announced the detection of a cosmic neutrino with a record energy of about 220 PeV, measured in the depths of the Mediterranean Sea.
This event is the most energetic neutrino ever observed and provides the first evidence that neutrinos of such high energies are produced in the Universe. After long and meticulous work to analyse and interpret the experimental data, on Wednesday 12th February, an article was published in Nature.
