You can't see, feel, hear, taste or smell them, but tiny particles from space are constantly raining down on us.

The handheld particle detector CosmicWatch is roughly the size of a box of animal crackers. Every time a muon passes through ...

Spencer Axani, assistant professor in the Department of Physics and Astronomy, is the inventor of CosmicWatch, a portable, ...

"WIMPs are still the leading candidate for dark matter, but billions of dollars of experiments have been done, only getting ...

The most powerful cosmic-ray electrons and positrons ever detected slamming into Earth's atmosphere carry energies so high they can only have come from relatively close by, new research has revealed.

Scientists have recently identified electrons and positrons with the highest energies ever recorded on Earth. They provide evidence of cosmic processes emitting colossal amounts of energy, the origins ...

A complete survey of all the particle and antiparticle activity that goes on during the Sun’s 11-year cycle has found previously unknown ways these particles behave. Cosmic rays coming from outside ...

New research suggests that these ultra-high energy rays derive their energy from magnetic turbulence. Ultra-high energy cosmic rays, which emerge in extreme astrophysical environments -- like the ...

A new experiment set for an Aug. 14 launch to the International Space Station will provide an unprecedented look at a rain of particles from deep space, called cosmic rays, that constantly showers our ...
