Juno's findings provide fresh evidence for how and where cosmic rays form.

When rockets fire into space, the insides of their engines become an extreme environment where temperatures soar and tiny ...

The study of these fast-moving particles provides significant clues about the early universe.

Our most powerful particle accelerators mimic near-light speeds of cosmic particles. But no upgrade may be capable of ...

By stacking custom-designed silver nanoparticles like nanoscale LEGO bricks, scientists stabilized a mysterious crystal phase that had never been observed before. The material not only solves a ...

In less than a millionth of a second after a nuclear detonation or a severe nuclear reactor accident, an enormous burst of ...

Scientists have discovered that ultraheavy atomic nuclei could explain some of the highest-energy cosmic rays ever observed.

Physicists know that their elegant theoretical description of forces and particles — the standard model of particle physics — must be incomplete, because there are a host of phenomena it cannot ...

Going to smaller and smaller distance scales reveals more fundamental views of nature, which means if we can understand and describe the smallest scales, we can build our way to an understanding of ...
