For years, astronomers have searched for the origins of ultra-high-energy cosmic rays, the most powerful particles in the universe. These energetic travelers move at nearly the speed of light, packing ...

Proving that the results reflected the flux of cosmic-ray muons wasn’t difficult. To turn the stacked pair of GM counters into a coincidence detector, I hooked up the output of each board (oddly ...

The use of artificial intelligence (AI) scares many people as neural networks, modeled after the human brain, are so complex ...

Opinion High energy neutrinos are the coolest particles in astrophysics. Born in distant cosmic cataclysms, they speed ...

Scientists suspect lightweight dark matter might ionize hydrogen in the Milky Way’s core. This could also explain the 511-keV ...

A strange energy source at the center of the Milky Way may be a new type of dark matter. Scientists found that hydrogen gas ...

A new technique in detector fabrication could change high-energy physics forever. By using additive manufacturing, ...

NASA powers down Voyager probes to save power. Instruments shut off to extend life, as the trailblazing spacecraft push the ...

“Since our detectors sit at the bottom of the sea ... Unlike light or charged particles (including the cosmic rays that produce them), they travel in straight lines, unbothered by magnetic ...
