Latest Cosmic ray Stories
An international team of scientists is working under Antarctica's snow-covered surface to build the world's largest neutrino telescope. The telescope -- called IceCube -- will occupy a cubic kilometer of Antarctica when it is completed in 2011, said University of Delaware Professor Thomas Gaisser, one of the project's lead scientists. IceCube will provide new information about some of the most violent and far-away astrophysical events in the cosmos, said Gaisser, who is managing the...
The physicists, engineers and technicians from the University of Delaware's Bartol Research Institute are part of an international team working to build the world's largest neutrino telescope in the Antarctic ice, far beneath the continent's snow-covered surface.
Take a gold sample the size of the head of a push pin, shoot a laser through it, and suddenly more than 100 billion particles of anti-matter appear.
A team of researchers in Canada have made a bold stride in the struggle to detect dark matter.
Data from the Ulysses spacecraft, a joint NASA-European Space Agency mission, show the sun has reduced its output of solar wind to the lowest levels since accurate readings became available. The sun's current state could reduce the natural shielding that envelops our solar system.
A new report published on Friday, 5 September, provides the most comprehensive evidence available to confirm that the Large Hadron Collider (LHC)'s switch-on, due on Wednesday this week, poses no threat to mankind.
NASA's newest observatory, the Gamma-Ray Large Area Space Telescope, or GLAST, has begun its mission of exploring the universe in high-energy gamma rays.
Students from OSUâ€™s Radiation Physics Laboratory built and successfully launched a cosmic radiation detector this summer that reached the edge of outer space.
Just as an impressionist artist makes an image from countless tiny strokes of paint, NASAâ€™s new Interstellar Boundary Explorer (IBEX) spacecraft will build up an image of the termination shock and areas beyond by using hits from high-speed atoms that are radiating out of this region.
By Mark Vierthaler, Journal-World, Lawrence, Kan. Jul. 7--Members of Kansas University's physics department now have a new tool to help them determine what effect cosmic rays may have on mass extinction.
The IceCube Neutrino Observatory is a neutrino telescope that is currently being built at the Amundsen-Scott South Pole Station. IceCube is being constructed in deep Antarctic ice by deploying thousands of PMTs (photomultiplier tubes) at depths of 4750 to 8000 feet. These spherical optical sensors are deployed on strings of sixty modules each, into holes melted by hot water drilling. Since 2005, 59 strings have been deployed and installation is expected to be complete by 2011. The strings are...
Gamma-Ray Astronomy -- Gamma-ray astronomy is the astronomical study of gamma rays. Long before experiments could detect gamma rays emitted by cosmic sources, scientists had known that the universe should be producing these photons. Work by Feenberg and Primakoff in 1948, Hayakawa and Hutchinson in 1952, and, especially, Morrison in 1958 had led scientists to believe that a number of different processes which were occurring in the universe would result in gamma-ray emission. These...
