A puzzling discovery in NGC 1068 shows a flood of neutrinos but weak gamma rays. Scientists now suspect helium atoms ...

Astronomers have developed a computer simulation to explore, in unprecedented detail, magnetism and turbulence in the ...

Cosmic particles with phenomenal energy have puzzled scientists for decades. A new theory may finally unveil their origin. Ultra-high-energy cosmic rays (UHECRs) surpass in power anything humans can ...

The assailant, seen right at the point of the break, could be a fast-spinning neutron star, known as a pulsar. Scientists ...

NASA’s Chandra X-Ray Observatory helped diagnose the cause behind a large kink in a huge filament near the center of the ...

In space, energetic neutrinos are usually paired with energetic gamma rays. Galaxy NGC 1068, however, emits strong neutrinos and weak gamma rays, which presents a puzzle for scientists to solve. A new ...

These high-energy particles are linked to powerful cosmic events such as exploding stars and the environments around black holes. Plus, they also play a role in atmospheric chemis ...

NASA's Chandra Observatory recently captured an X-ray image that helped identify a dramatic break in one of the galaxy's ...

Magnetar flares, colossal cosmic explosions, may be directly responsible for the creation and distribution of heavy elements across the universe, suggests a new study.

This acceleration involves particles repeatedly crossing shock ... the study validates models used to interpret cosmic ray origins and supernova remnants. Moreover, the experiment's design ...

Astronomers have discovered a likely explanation for a fracture in a huge cosmic "bone" in the Milky Way. Using NASA’s ...

In a new study, published in Science, researchers have detected a cosmic ray offshoot called a neutrino or ghost particles. These parties are considered so evasive that they interact with anything ...
