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 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 ...

Five pocket mice traveled around the Moon on Apollo 17 in 1972. These animals carried radiation detectors implanted beneath ...

The mysterious Amaterasu particle may not be a proton at all. New research suggests that some of the most extreme cosmic rays could be ultraheavy atomic nuclei, heavier than iron, which are better ...

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 ...

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.

Enormous black holes in galaxies millions of light years away are pelting us with energetic particles. The finding, from a telescope array 10 times the size of Paris, solves a long-standing mystery ...

Cosmic rays are high-energy charged particles, predominantly protons and atomic nuclei, that permeate the Galaxy. As they traverse the interstellar medium, they encounter gas, dust and photon fields, ...

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 ...
