The largest digital camera on Earth has started a ten-year survey of the universe from its perch atop a mountaintop in Chile.

A neutrino from space recently plunged into the Mediterranean Sea with an energy that blows all other known neutrinos out of the water. Packing a punch of some 220 million billion electron volts, this ...

A researcher at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, has published a ...

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 ...

Some of the most energetic cosmic rays in the galaxy may come from a surprisingly small source. If Max Planck Institute for Astrophysics researcher Laura Olivera-Nieto and her colleagues are right, ...
