Cosmic rays, predominantly high-energy particles originating from outside the Solar System, interact with Earth’s atmosphere to produce a complex radiation environment. This continuous bombardment ...

How much light has been emitted by all galaxies since the cosmos began? After all, almost every photon (particle of light) from ultraviolet to far infrared wavelengths ever radiated by all galaxies ...

There is a clear statistical correlation between global seismic activity and changes in the intensity of cosmic radiation recorded at the surface of our planet, potentially helping to predict ...

The study of cosmic ray anisotropy and magnetic fields lies at the intersection of astrophysics and plasma physics, revealing subtle imprints of the turbulent interstellar medium and the local ...

Earth’s magnetic field cocoons our planet from the onslaught of cosmic radiation streaming through space while also shielding us from charged particles hurled outward by the sun. But the geomagnetic ...

Peter Rejcek, Antarctic Sun Editor: The U.S. Antarctic Program’s longest running experiment, which helps keeps an eye on the activity of the solar system’s hottest object, will soon be working in the ...

NASA: Planning a trip to Mars? Take plenty of shielding. According to sensors on NASA’s ACE (Advanced Composition Explorer) spacecraft, galactic cosmic rays have just hit a Space Age high. NASA: ...

Our planet has recently been struck by an extraordinary burst of cosmic rays, demonstrating an intensity level that is unparalleled in recorded history. As we delve into the specifics of this event, ...

Cosmic rays are particles from outer space that travel across the universe. They can be made by the sun, by other stars exploding, and even black holes. They move extremely fast, nearly the speed of ...

At 10 a. m. on Jan. 1 the high-banked seats of a lecture amphitheatre at Washington University were jammed with a capacity crowd of 300—mostly scholars, a few newshawks, a handful of laymen. In the ...

Astronomers have succeeded in quantifying the proton and electron components of cosmic rays in a supernova remnant. At least 70% of the very-high-energy gamma rays emitted from cosmic rays are due to ...
