Highly energetic and difficult to detect, neutrinos travel billions of light years before reaching our planet.

Although it is known that these elementary particles come from the depths of our universe, their precise origin is still unknown.

Cosmic rays' birthplaces produce neutrinos.

Neutrinos are neutral particles difficult to detect.

They have almost no mass and hardly interact with matter.

They race through the universe and can travel through galaxies, planets and the human body almost without a trace.

"Astrophysical neutrinos are produced exclusively in processes involving cosmic ray acceleration," explains astrophysics Professor Sara Buson from Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany.

This is precisely what makes these neutrinos unique messengers paving the way to pinpoint cosmic ray sources.
