Supermassive black holes are some of the most powerful engines in the universe. These giants sit at the centers of galaxies, ...

Cosmic rays may play a role in triggering lightning on Earth, a new study suggests. | Credit: Jan Drahokoupil / 500px / Getty Images Cosmic rays may offer an out-of-this-world answer to a long ...

This resulted in an unparalleled set of statistical data for analyzing cosmic-ray electrons. The team confirmed that the electron energy spectrum extends up to at least 40 TeV, which is 400 times ...

New research reports the most powerful cosmic rays ever detected ... the scientists created an energy spectrum for the rays hitting Earth in unprecedented detail. The quantities of these rays ...

They clearly observed a bending structure in the gamma-ray spectrum at tens of TeV, indicating the acceleration limit of cosmic rays in this region. The energy spectrum measured by LHAASO can be ...

Scientists at an observatory in southwestern China say they have identified a super cosmic ray accelerator – a discovery that could fundamentally change understanding of the origin and source of ...

Measurements of cosmic rays in past decades have revealed a break around 1 PeV in the energy spectrum, which is called the "knee" of the cosmic ray energy spectrum due to its shape resembling a ...
