How common are Earth-like planets in the universe? When I started working on supernova explosions, I never imagined that my ...

A complete survey of all the particle and antiparticle activity that goes on during the Sun’s 11-year cycle has found previously unknown ways these particles behave. Cosmic rays coming from outside ...

Beyond better testing, we need better protection. Physical shields seem like the obvious first defense. Hydrogen-rich ...

The study of cosmic rays and heliospheric physics bridges our understanding of high‐energy particles from distant astrophysical sources and the dynamic environment shaped by the solar wind and ...

Composite image of the Tycho Supernova remnant. Shock waves from such explosive events are believed to be the main drivers behind cosmic rays. Scientists have come a step closer to understanding how ...

The most powerful cosmic-ray electrons and positrons ever detected slamming into Earth's atmosphere carry energies so high they can only have come from relatively close by, new research has revealed.

Scientists have recently identified electrons and positrons with the highest energies ever recorded on Earth. They provide evidence of cosmic processes emitting colossal amounts of energy, the origins ...

The investigation of cosmic rays and their potential connection with dark matter occupies a central role in contemporary astrophysics. Recent experimental and theoretical advances have refined our ...

Astronomers at the University of North Carolina at Chapel Hill have helped uncover new clues about the longest-lasting cosmic explosion ever observed, a gamma-ray burst that lasted nearly seven hours.

Energetic particles that pop briefly into existence when cosmic rays hit Earth’s atmosphere could help assess hidden damage to buildings in Ukraine after the war ends. These particles — known as muons ...
