Latest Cosmic ray Stories
A new study based on data from ESA's Cluster mission has revealed that the bow shock formed by the solar wind as it encounters Earth's magnetic field is remarkably thin: it measures only 17 kilometers across.
Our understanding of how clouds form may need to be revised, according to new research published in the journal Nature.
A new Chinese experiment could help explain why matter predominates over antimatter in the universe.
For the first time, researchers have confirmed the existence of antimatter in the Earth's magnetosphere.
The radioactive decay of uranium, thorium, and potassium contained in the Earth's crust provides nearly half of the planet's internal heat.
NASA said on Thursday that its Voyager spacecraft has helped to show that the edge of our solar system may not be smooth, but filled with a turbulent sea of magnetic bubbles.
NASA will host a media teleconference at 1 pm EDT on Thursday, June 9, to discuss a new computer model that shows the edge of our solar system is not smooth, but filled with a turbulent sea of magnetic bubbles.
After successfully docking with the International Space Station, the Endeavour and station crews wasted no time getting down to business installing a $2 billion cosmic ray detector with the goal of scanning the invisible universe for years to come.
MESSENGER carries a Gamma-Ray Spectrometer (GRS) that is capable of measuring and characterizing gamma-ray emissions from the surface of Mercury.
Physicists at Rice University and their collaborators have detected the antimatter partner of the helium nucleus, antihelium-4.
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...
