Five pocket mice traveled around the Moon on Apollo 17 in 1972. These animals carried radiation detectors implanted beneath ...
When a star dies, it generates an explosion of elemental nuclei and hurls them into space. Those elements, called cosmic rays, travel at nearly the speed of light, and eventually some of them ...
Milestone results released by the Large High Altitude Air Shower Observatory (LHAASO) on November 16 have solved a decades-old mystery about the cosmic ray energy spectrum—which shows a sharp decrease ...
Scientists have identified LHAASO J1912+1014u as a cosmic accelerator that can push protons beyond one quadrillion electron volts. The finding may help reveal where the Milky Way’s most energetic ...
Everything on the electromagnetic spectrum has some properties of both waves and particles, but it’s difficult to imagine a radio wave, for example, behaving like a particle. The main evidence for a ...
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 ...
Scientists have identified an accelerator that produces the highest-energy protons in our galaxy, a finding that could clarify the nature of the fast-moving particles filling the space between stars.
