Neutrinos detected on Earth
The Ice-Cube Laboratory at the Amundsen-Scott South Pole Station in Antarctica is the world’s largest neutrino detector. The computers collect raw data on neutrino activity from its sensors that are in the ice and the light that emits when the neutrinos strike. High energy subatomic particles called neutrinos from beyond our solar system have detected on Earth that for the first time ever. Researchers have been involved to say that “ the discovery will open up a new area of astronomy and will have the potential answer a question that has puzzled astronomers for at least a century. The question is “Where do cosmic rays come from?’
Darren Grant at University of Albert physicist said “It really is the dawn of a new field.” He was part of the international scientific collaboration called Ice-Cube that had reported the recent detection of 28 extremely high-energy neutrinos that were in Antarctica that are now thought to have come from space. The results of this new detection were published online on Thursday in the journal of Science. The astrophysicists had theorized that the extremely high-energy neutrinos were more energetic than any produced on Earth or by the Sun and would be blasted out by the same catastrophic events(such as black holes, supernovas, pulsars, or even galactic nuclei) in deep space that are thought to generate cosmic rays.
Now Grant says “Scientists have finally detect some. They’re the highest energy neutrino events that have ever been recorded and measured… It is proof that they came from outside of the Earth. Two neutrinos have energies above a whopping peta electron volt that is 125 times the 8 tetra-electron-volt energy of the record proton collisions that have been generated by the world’s biggest particle accelerator, it is called the Large Hadrian Collier, and the billions of times the energy of the neutrinos are produced by the Sun.
