Scientists detect cosmic neutrinos from supernova, black holes in Antarctica.Scientists have confirmed the presence of cosmic neutrinos buried deep with Antarctic’s ice sheets. These tiny, energetic particles called neutrinos could have arrived from galaxies such as our Milky Way and beyond
Antarctica Scientists Confirm Existence of Cosmic Neutrinos.Buried deep in the Antarctic ice, an observatory has spotted ghostly, nearly massless particles coming from inside our galaxy and points beyond the Milky Way.
Finding these cosmic neutrinos not only confirms their existence but also sheds light on the origins of cosmic rays, the researchers said.
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. [See Photos of the IceCube Observatory Buried in Ice]
Dark Pion Particles May Explain Universe’s Invisible Matter.Dark matter is the mysterious stuff that cosmologists think makes up some 85 percent of all the matter in the universe. A new theory says dark matter might resemble a known particle. If true, that would open up a window onto an invisible, dark matter version of physics.
