when the highest energy neutrino has been detected by a team of international researchers. In fact, it has 30 times more energy than has been detected so far. Researchers still do not know the origin of the neutrino, but they believe it would have come from outside the solar system. This was reported in the journal Nature.

They explain that the KM3Net submarine telescope has received evidence of neutrinos. The telescope is located in the deepest sea and consists of two parts: The ARCA detector, from Sicily, geared towards neutrino astronomy, and the ORCA, near the French Mediterranean, to measure atmospheric neutrino ratios. Interaction of a neutrino around the detector results in charged particles emitting light radiation.

Thus, KM3NeT/Arca has detected a very high energy muon. In terms of energy and direction, the researchers conclude that it is a neutrino of cosmic origin. According to them, this detection has opened the door to new astronomical observations that will allow us to know the high-energy universe.

The high-energy universe is a place of extremely violent events, and among the particles produced there are the high-energy neutrinos. For example, what they have now detected has been suggested that it may have arisen during the collision of cosmic rays against background microwave radiation protons. It is anticipated that once the KM3NeT telescope is completed, they will receive a large amount of information about this type of event, with even greater precision, which will bring a great deal of knowledge in the research of the universe.
