Cosmic rays' power source has long remained a mystery, yet new research may finally provide the answer to where particle ...

NTNU researchers may have found the answer to one of the big, unanswered questions in physics. The universe is full of ...

The most mysterious of these are ultra-high-energy cosmic rays (UHECRs), which exceed 10¹⁸ electron volts (eV) in energy.

Have you ever had an X-ray taken of your bones? Well, so has the Milky Way. NASA's Chandra X-ray Observatory regularly images our home galaxy, and a recent scan caught something that might be familiar ...

Cosmic rays are a baffling and complex phenomenon ... Iofgren, E. P. Ney and F. Oppenheimer of the University of Minnesota told a conference at Madison, Wis. how they sent automatic Wilson ...

"This is an important result, as we can conclude that the measured CRe [cosmic ray electrons] most likely originate from very few sources in the vicinity of our own solar system, up to a maximum ...

The most powerful cosmic rays that we see on Earth may come from microquasars, small black holes that blast out jets of material from orbiting stars. Unlike larger quasars, which feature a ...

This is what first led experts to speculate that cosmic collisions could also create long gamma-ray bursts under certain circumstances.

Many of the gamma rays we see coming from the sun are produced by cosmic rays, which are charged particles that hurtle through space at incredible speeds. When cosmic rays hit the sun, the ...
