Imagine a super-advanced alien civilization that needs insane amounts of energy way beyond our puny solar panels and wind turbines to power their mega-cities, AI overlords, or whatever interstellar ...

Cosmic rays seen at Earth show a wide range of particle energies, from 10 7 electron-volts (eV) to more than 10 20 eV, the latter being about the same as the kinetic energy of a 450 gram football ...

Cosmic rays traveling through space may provide enough energy to sustain life even in incredibly cold and dark environments, a new study suggests. The staggeringly energetic neutrino likely came from ...

More than 600 feet below the surface of Antarctica, ultrasensitive detectors picked up the tracks of cosmic rays crashing down from outer space. The Askaryan Radio Array is a group of sensors drilled ...

Scientists studying mysterious ultra-powerful cosmic rays have uncovered a surprising hidden pattern that could finally help explain where these particles come from. Using the DAMPE space telescope, ...

Millions of light-years away, millions of years ago, a star exploded. In this violent process, it ejected incredible amounts of mass, including carbon, nitrogen and oxygen—the building blocks of life.

Earth is constantly being bombarded by particles from space, but the most energetic arrivals are difficult to understand because scientists rarely observe them directly. Instead, researchers usually ...

Weird jellyfish? Or something weirder? (NASA/JPL Caltech) NASA rovers Curiosity and Perseverance have photographed some pretty strange objects on the surface of Mars. From human-like heads and ...

Add Yahoo as a preferred source to see more of our stories on Google. CERN recreated high-energy cosmic ray collisions with oxygen, exposing major gaps in models of particle showers in Earth's ...
