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 ...

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 ...

This week's science news.

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 ...

For nearly a century, astronomers have known that the universe is expanding. In the late 1990s, two independent teams, the ...

Scientists still don’t know where ghostly particles called neutrinos originate. A distant galaxy could be a potential source.

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 ...

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 ...

"With the launch of the ten-year Legacy Survey of Space and Time, the Rubin Observatory is opening a new window on the ...
