This week's science news.

The biggest and best movie of the universe began production this week—at the new Vera C. Rubin Observatory in Chile, rather ...

In 1991, an experiment detected the highest-energy cosmic ray ever observed. Later dubbed the Oh-My-God particle, the cosmic ray’s energy shocked astrophysicists. Nothing in our galaxy had the power ...

More than one million sources of energy are featured in the first X-ray images from the eROSITA space telescope. By Laura Baisas Published Feb 5, 2024 12:00 PM EST Add Popular Science (opens in a new ...

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 ...

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, ...

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 ...

There may be an ultraheavy explanation for the mystery surrounding the origins of the highest-energy particles ever observed. Ultrahigh-energy cosmic rays are particles from space that strike Earth ...

Scientists from the Telescope Array Collaboration have detected an ultrahigh-energy cosmic ray, a discovery that’s challenging our current understanding of exotic cosmic phenomena and their origins.

Galactic cosmic rays — high-energy particles from outside the solar system — could theoretically power life on certain frigid worlds. The radiation can trigger chemical reactions underground, whose ...
