Exactly how these odd particles get their teeny-tiny bit of mass is unknown, but scientists believe they originate from the high-energy environments of exploding stars and black holes located at the distant edges of the Milky Way and beyond.

Scientist around the globe are now looking for new anomalies in law of physics, because of the detection of cosmic neutrinos, which came from most violent phenomena in the universe, such as black holes.
The Neutrinos themselves were first discovered at the IceCube Neutrino Observatory, which comprises of 86 shafts that burrow 8,000 feet into the ice close to the South Pole.
But while the new observations confirm the existence of astrophysical neutrinos and the means to detect them using the IceCube Observatory, actual point sources of high-energy neutrinos remain to be identified.
“These neutrinos may give us an understanding about the origin of the most energetic processes in the universe”, said scientists.
The new study that detected 21 ultra high energy muons – representing secondary particles that are created on those rare occasion on which neutrinos interact with the other particles – provide independent confirmation on astrophysical neutrinos in our galaxy and cosmic neutrinos from sources external to the Milky Way.
Between May 2010 and May 2012, the observatory detected more than 35,000 neutrinos.
Detectors sunk deep into the ice of Antarctica have caught neutrinos oscillating at high energies.
According to Vladimir Papitashvili, an astrophysics experts at the Nationwide Science Basis’s (NSF) Division of Polar Packages, the Observatory was built with the help of funding agencies from various countries of the world. This could happen only if their sources were outside our galaxy. While this topic is not discussed at length in their study, they said that the data appears to show that they do not come from gamma-ray bursts or active galactic nuclei, though more research is needed to know for sure.
This is significant because of what the neutrino can tell us about the universe by analyzing the time it took to travel to Earth.
The IceCube researchers concentrate on muon neutrinos since these continue to travel forward for several kilometers after the initial neutrino collision event.
The research station published their results on Thursday in Physical Review Letters, saying the results were “unequivocal” in showing that neutrinos have “traversed space” and landed on earth.
“It is sound confirmation that the discovery of cosmic neutrinos from beyond our galaxy is real,” he concludes.
The new observations were spotted by pointing the IceCube Observatory through the Earth to spot activity in the Northern Hemisphere sky.
This is where the IceCube Lab at the South Pole plays a vital role.

Physics professor, Albrecht Karle suggests that at least one fraction of the flux had extragalactic origin. The researchers searched for neutrinos boasting similar energies and coming from all directions at similar rates.
