Latest Cosmic ray Stories
A new study has resurrected the hypothesis that cosmic rays may influence cloud formation on Earth.
A new observatory has begun formal operations in Mexico. The High-Altitude Water Cherenkov Gamma Ray Observatory is designed to study the origin of very high-energy cosmic rays and observe the most energetic objects in the known universe.
According to a new analysis from scientists at the University of Maryland, Voyager 1 has finally left the solar system – marking the first time a manmade object has entered the Milky Way outside of the Sun’s influence.
Scientists are split on exactly where NASA's Voyager 1 spacecraft is sitting within the Solar System, but new research from the space agency suggests it is on the last frontier out.
Researchers from NASA and the University of New Hampshire believe they have shed a light on the cosmic activity occurring on the dark side of the moon.
A new study reports that data collected by NASA's Lunar Reconnaissance Orbiter (LRO) reveals that lighter materials like plastics provide effective shielding against the radiation hazards faced by astronauts during extended space travel.
For decades scientists have wondered whether a mysterious form of matter – known simply as Dark Matter since it does not interact directly with light – makes up the majority of the “stuff” in the Universe.
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...
