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 ...

Scientists are using cutting-edge techniques to track water ice on the Moon—an essential resource for future space missions.

In a study published in Physical Review Letters, the HESS consortium describes the detection of these record-breaking cosmic rays. Due to their energy loss during interstellar travel, these ...

(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 ...

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 ...

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, ...

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