A team of scientists at the IceCube Neutrino Observatory in Antarctica claimed that they discovered high-energy neutrinos present deep within the ice sheet. According to the team, some of those particles produce pions, neutrinos and photons.

Researchers associated with the finding said the discovery of these cosmic neutrinos not only confirms their existence, but also shed light on the origins of cosmic rays. As per reports, the IceCube Neutrino Observatory is made up of 86 shafts dug 8,000 feet into the ice near the South Pole. The shafts are equipped with detectors that look for the telltale light from high-energy particles plowing through the surrounding ice.

According to experts, neutrinos have very less mass. These elusive particles come from high-energy sources like exploding stars, black holes and galactic cores among them, they said.

They said these particles do not interact much with matter, occasionally only one will hit an atomic nucleus on Earth and when that happens, the neutrino generates a particle called a muon.

According to Francis Halzen, principal investigator of IceCube and professor of physics at the University of Wisconsin-Madison, when looking for neutrinos, scientists usually search for these muons.

According to the scientists, the muons move faster than the speed of light in a solid and generate light waves, like the wake of a boat in water, called Cherenkov radiation. They also show the paths of the neutrinos.

The IceCube project found neutrinos from outside our galaxy in 2013, but to confirm that detection the researchers, led by a team at the University of Wisconsin-Madison, had to make sure these neutrinos weren't coming from sources within our own galaxy.
