Latest Cosmic ray Stories
One of the most complex space scientific instruments ever built, the Alpha Magnetic Spectrometer (AMS-02) arrived at the Kennedy Space Center in Florida on Friday, escorted by astronauts who will fly with it on the Space Shuttle in February 2011.
Though still under construction, the IceCube Neutrino Observatory at the South Pole is already delivering scientific results â€” including an early finding about a phenomenon the telescope was not even designed to study.
Scientists leading an underground experiment to discover dark matter may be forced to relocate to a location even deeper below the Earth's surface.
An international team including scientists from Princeton University has detected subatomic particles deep within the Earth's interior.
In a large natural disaster, such as the Haitian earthquake earlier this year, or in an unsolved homicide case, knowing the birth date of an individual can guide forensic investigators to the correct identity among a large number of possible victims.
A lightning researcher at the University of Bath has discovered that during thunderstorms, giant natural particle accelerators can form 40 km above the surface of the Earth.
New images from NASA's Fermi Gamma-ray Space Telescope show where supernova remnants emit radiation a billion times more energetic than visible light.
Physicists may have glimpsed a particle that is a leading candidate for mysterious dark matter but say conclusive evidence remains elusive.
The solar system is passing through an interstellar cloud that physics says should not exist.
New information about lightning-emitted X-rays, gamma rays and high-energy electrons during thunderstorms is prompting scientists to raise concerns about the potential for airline passengers and crews to be exposed to harmful levels of radiation.
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...
