Latest Cosmic ray Stories
NASA's space shuttle program is winding down. With only about half a dozen more flights, shuttle crews will put the finishing touches on the International Space Station (ISS), bringing to an end twelve years of unprecedented orbital construction. The icon and workhorse of the American space program will have finished its Great Task.
Astronomers recently observed a mysterious flux of particles in the universe, and the hope was born that this may be the first observation of the remnants of "dark matter".
Four Miami-area high school students have an unusual summer job on their resumes: building a cosmic ray detector alongside nuclear physicists.
Florida Institute of Technology researchers are trying to solve one of the great mysteries in nature: how thunderstorms make lightning.
Researchers at North Carolina State University have used a mathematical model that allows them to get a clearer picture of the galaxy's youngest supernova remnant by correcting for the distortions caused by cosmic dust.
British scientists say they've detected cosmic rays reaching an underground detector that reflect major weather events occurring in the Earth's stratosphere. The researchers said the cosmic-rays detected half a mile underground in a unused U.S.
Cosmic-rays detected half a mile underground in a disused US iron-mine can be used to detect major weather events occurring 20 miles up in the Earthâ€™s upper atmosphere, a new study has revealed.
NASA and the National Science Foundation have successfully launched and demonstrated a newly designed super pressure balloon prototype that may enable a new era of high-altitude scientific research.
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 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...
