There may be an ultraheavy explanation for the mystery surrounding the origins of the highest-energy particles ever observed.

A long-standing cosmic mystery is beginning to yield new clues as researchers uncover a strikingly consistent pattern in the ...

A major physics experiment has uncovered evidence for a strange new form of matter, where a fleeting particle gets trapped inside a nucleus. This exotic state may reveal how mass is generated, ...

A century after their discovery, cosmic rays—particles of extreme energy originating from the far reaches of the ...

Colloidal control: A patterned magnetic layer and tailored external fields enable precise, size-based manipulation of ...

New cosmic ray theory: Researchers suggest ultraheavy atomic nuclei may explain the origins of the highest-energy cosmic rays ever detected. Why it matters: Ultraheavy nuclei could survive longer ...

From mysterious dark matter to the radioactive decay of atomic nuclei, the past 12 months have reiterated just how strange particle physics can be. When you purchase through links on our site, we may ...

Cosmic rays (CRs) are energetic particles traveling through space at speeds close to that of light. They consist of atomic nuclei, electrons, positrons, high-energy gamma rays, and neutrinos, and are ...

New research suggests a particle inside an atom can lose mass, offering a fresh look at how matter works at the smallest ...

Physicists have found a new way to study the shape of atomic nuclei — by obliterating them in high-energy collisions. The method could help scientists to better understand nuclei’s shapes, which, for ...
