A groundbreaking discovery has rocked the field of neutrino astronomy—scientists have detected an ultra-high-energy neutrino ...

Want to see cosmic rays? You might need a lot of expensive exotic gear. Nah. [The ActionLab] shows how a cup of coffee or cocoa can show you cosmic rays — or something — with just the right ...

(We’ve since learned that they are particles, not rays, but the name stuck.) There are several ways to detect cosmic rays. You can look for them directly—whether on the ground or above the ...

Astronomers have long been puzzled by two strange phenomena at the heart of our galaxy. First, the gas in the central ...

While neutrinos remain some of the universe’s most enigmatic particles, each new detection brings scientists closer to ...

An interaction between a cosmic ray and the CMB would have created a shower of high-energy neutrinos. If that is the case, this would be the first detection of a so-called "cosmogenic neutrino." ...

Scientists from the University of Tokyo and NEC Corp. noted that cosmic-ray muons readily pass through ... to monitor magma movement in a volcano, detect empty cavities in the Great Pyramid ...

Gamma-ray bursts (GRBs) are the most energetic events ever observed in the universe. These powerful outbursts can shine a ...

Scientists have revealed a hidden trigger of lightning that could resolve a centuries-old weather mystery. Earth is struck by some 44 bolts of lightning each second, on average. Despite this, ...

Want to see cosmic rays? You might need a lot of expensive exotic gear. Nah. [The ActionLab] shows how a cup of coffee or cocoa can show you cosmic rays — or something — with just the right ...

Cosmic rays batter our planet all the time, but their impacts are quite hard to detect. "We would really like to have direct simultaneous observations of the two phenomena — lightning and cosmic ...

We still don't fully understand what triggers lightning. A new study suggests that showers of cosmic rays may be the missing link. Cosmic rays may offer an out-of-this-world answer to a long ...
