Latest Cosmic ray Stories
Astronauts anticipate more trips to the moon and manned missions to Mars, but exposure to cosmic radiation outside the Earthâ€™s magnetic field could be detrimental to their arteries.
In a paper to be published in the April 10, 2011, issue of The Astrophysical Journal, scientists on NASA's Interstellar Boundary Explorer (IBEX) mission, including lead author Nathan Schwadron and others from the University of New Hampshire, isolate and resolve the mysterious "ribbon" of energy and particles the spacecraft discovered in the heliosphere â€“ the huge bubble that surrounds our solar system and protects us from galactic cosmic rays.
Pattern of X-ray 'stripes' in supernova remnant could explain how cosmic rays are produced.
NASA and the National Science Foundation launched a scientific balloon on Monday, Dec 20, to study the effects of cosmic rays on Earth.
Raimund Muscheler is a researcher at the Department of Earth and Ecosystem Sciences at Lund University in Sweden.
Search for ultra high energy neutrinos from space turns the moon into part of the 'detector'.
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.
About eight months before the NASA rover Curiosity touches down on Mars in August 2012, the mission's science measurements will begin much closer to Earth.
Searching below the surface of Antarctica for the mysterious neutrino.
The Alpha Magnetic Spectrometer-2 (AMS) destined for the International Space Station already is collecting cosmic ray signatures, even as it sits in a work stand at the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, said Prof Samuel Ting, the principal investigator for the program.
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...
