«Neutrino» are almost «ghost» particles.capable of crossing entire planets without stopping, and an extraordinarily mysterious oneloaded with a gigantic energy far superior to any previously detected, was captured in the Mediterranean in 2023; Today scientists place its origin in distant galaxies.
That «neutrino», captured thanks to an underwater detector off the coast of Sicily, surprised the scientific community due to the exceptional characteristics it had (especially due to the record energy load never seen before) and hundreds of scientists from various institutions undertook a meticulous investigation to try to establish its origin; Now, March 9, 2026, they publish their conclusions in the Journal of Cosmology and Astroparticle Physics.
The researchers point out, as the most probable hypothesis, that its origin is in distant blazars, galaxies with giant black holes that launch jets of energy in the direction of the Earth, which would demonstrate that the universe can create much more powerful particles than previously believed, and would help to understand some of the most violent phenomena that occur in the cosmos and to understand the invisible, since neutrinos do not interact with almost anything and they report different information than that coming from light or X-rays.
A European research infrastructure at the bottom of the Mediterranean Sea (called KM3NeT) houses underwater telescopes capable of detecting neutrinos from space or the Earth’s own atmosphere, and one of its devices recorded in 2023 the most extraordinary captured to date, with an energy they estimated at 220 PeV, which means it is 40,000 times more powerful than the most powerful neutrinos from the Sun.
A powerful and mysterious neutrino
The researchers simulated all the events that could have occurred and that could justify the arrival on Earth of that giant but invisible particle and then compared the results with real observations, and among their numerous experiments they simulated a «population» of blazars using open source software with physically motivated parameters, with the parameters adjusted to values already known from other observations.
And they thus confirmed how these distant blazars are a plausible source of ultra-high energy neutrinos like the one captured in the Mediterranean, and the scientists have stressed that although it is the most promising hypothesis it will still need to be tested with new data, although they have assessed that a new window is opening for knowledge of the Universe.
The researchers looked for known signs of an explosion or a specific event that occurred in the Universe using radio, They place it in the distant blazars.
To understand what neutrinos are, scientists often use the simile of tennis balls, which collide and bounce against any physical object; but among them there are some «ghost» balls that go through everything without stopping; they come from space (from the Sun, star explosions or black holes) and they are everywhere. The one detected in 2023 in the Mediterranean, more than the size of a ball, would have the a great vehiclebut it would be equally invisible.
