Latest Cosmic ray Stories
According to a new study, black hole cosmic radiation blasted into the Earth back in the 8th century. Japanese astrophysicist Fusa Miyake discovered last year clues for the strange event located in the rings of ancient cedar trees that dated back to either 774 or 775 AD.
Science teachers in grade school sometimes hand out "mystery boxes," which contain ramps, barriers and a loose marble. Rotating the marble and feeling it hang up or drop, the students begin to deduce the contents of the box.
Physicists at Los Alamos National Laboratory are looking to cosmic rays from space to help diagnose damaged nuclear reactors like the one at the Fukushima Daiichi plant in March 2011.
Celebrating its 35th anniversary in space today, NASA’s Voyager 1 spacecraft is about to cross the threshold of our solar system, to boldly go where no man, nor machine, has ever gone before.
The levels of high-energy cosmic rays originating from outside our solar system and the levels of lower-energy particles originating from within have been undergoing changes at a faster rate than at any other time in the past seven years.
After several decades of making a lonely journey across our solar system, Voyager 1 has signaled to NASA that it may have reached the edge of interstellar space.
NASA said that its Fermi Gamma-ray Space Telescope detected the highest-energy light ever associated with an eruption on the sun on March 7.
When the sun launched a moderate, or M-class, solar flare May 17, 2012, it was still one of the largest eruptions seen since late January when our star began to rouse from an anomalously long quiet period.
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...
