WASHINGTON (Reuters) – A breakthrough in the study of ghostly particles called high-energy neutrinos that traverse space, zipping unimpeded through people, planets and whole galaxies, is giving scientists an audacious new way to expand our understanding of the cosmos. The IceCube Laboratory is pictured at the Amundsen-Scott South Pole Station, in Antarctica, in 2017 and

In this artistic rendering, a blazar is accelerating protons that produce pions, which produce neutrinos and gamma rays. Neutrinos are always the result of a hadronic reaction such as the one displayed here. Gamma rays can be produced in both hadronic and electromagnetic interactions.IceCube/NASA One of the great mysteries in science is determining not only

Finally, scientists have found the source for a high-energy cosmic neutrino coming from outside our galaxy. The so-called mysterious “ghost particle”, detected on 22 September 2017, travelled 4 billion light-years to reach us, originating from an extremely energetic object called a blazar. It’s an amazing discovery, one that not only confirms blazars as a source
