BEIJING, Sept. 29 (Xinhua) -- The following are the highlights of China's key technology news from the past week: COSMIC RAYS An international research team has conducted a precise measurement of the spectrum of protons, the most abundant component of cosmic rays, in an energy range from 40...

A very rapidly moving particle of extraterrestrial origin, especially one that collides with the earth's atmosphere. Cosmic rays are mainly protons and alpha particles but sometimes are other light atomic ...
WASHINGTON, Sept. 21 (Xinhua) -- Scientists on Thursday confirmed that cosmic rays with the highest energies that bombard the Earth originated from outside our Milky Way galaxy. In a paper published in the journal Science, a group of more than 400 scientists from 18 nations, reported that th...
Today, we call those particles cosmic rays. Now, H.E.S.S. scientists are excited because they’ve detected the highest energy electrons and positrons to date (a positron is like the "opposite" of an electron because it has the mass of an electron, but is positively charged like a ...
X-rays and gamma-rays detected by these balloons are “secondary cosmic rays,” produced by the crash of primary cosmic rays into Earth’s upper atmosphere. They trace radiation percolating down toward our planet’s surface. The energy range of the sensors, 10 keV to 20 MeV, is similar to...

Cosmic rays, first discovered in 1912, have been an enigma for years, but their detectability means they can be studied by middle and high school students with a basic knowledge of physics. CPPCC member Yang Jia, also a professor and a member of the Jiu San Society, a democratic political...
Tanaka’s new proposal is designed to defeat eavesdroppers by instead turning to a natural and ever-present resource of randomness: cosmic-ray muons. Cosmic rays, which are mainly protons, rain down on the Earth from deep space and generate showers of pions and other particles when they collide...
Toyota has - and we're really, really not making this up - called in NASA's engineering team to investigate whether cosmic rays could have been responsible for the mysterious ‘stuck accelerator' scandal that has plagued the manufacturer in recent months.Cosmic rays. Rays from space. It ...
