The Era of Neutrino Astronomy has Begun

COLLEGE PARK, Md. – Astrophysicists using a telescope embedded in Antarctic ice have succeeded in a quest to detect and record the mysterious phenomena known as cosmic neutrinos – nearly massless particles that stream to Earth at the speed of light from outside our solar system, striking the surface in a burst of energy that can be as powerful as a baseball pitcher’s fastball. Next, they hope to build on the early success of the IceCube Neutrino Observatory to detect the source of these high-energy particles, said Physics Professor Gregory Sullivan, who led the University of Maryland’s 12-person team of contributors to the IceCube Collaboration.

“The era of neutrino astronomy has begun,” Sullivan said as the IceCube Collaboration announced the observation of 28 very high-energy particle events that constitute the first solid evidence for astrophysical neutrinos from cosmic sources.  (more…)

NSF Signs $34.5-million Operating Agreement With University Of Wisconsin as Antarctic Neutrino Detector Nears Completion

The National Science Foundation has signed a five-year, $34.5-million agreement with the University of Wisconsin-Madison to operate a unique telescope–a cubic kilometer in volume–buried in the Antarctic ice sheet between 1,400 meters and 2,400 meters deep.

The collaborative agreement covers the cost of operating the IceCube Neutrino Observatory, located in the ice under the U.S. Amundsen-Scott South Pole Station. The observatory records the rare collisions of neutrinos, elusive sub-atomic particles, with the atomic nuclei of the water frozen into ice. Neutrinos come from the sun, cosmic rays interacting with the Earth’s atmosphere, and dramatic astronomical sources such as exploding stars in the Milky Way and other distant galaxies. Trillions of neutrinos stream through the human body at any given moment, but they rarely interact with regular matter, and researchers want to know more about them and where they come from. (more…)
