By tracing solar flare gamma rays, scientists gain new insight into particle behavior that shapes space weather forecasts.

Crepuscular rays are beams of sunlight that appear to radiate from the Sun when it shines through gaps in clouds or terrain, ...

Scientists at the Paul Scherrer Institute PSI have, for the first time, demonstrated a technique that synchronizes ultrashort X-ray pulses at the X-ray free-electron laser SwissFEL. This achievement ...

Ray tracing and path tracing sound similar — and technically, they are. Both methods simulate how light travels in a 3D environment, but the way they work and the results they produce are completely ...

Scientists at the X-ray free-electron laser SwissFEL have realized a long-pursued experimental goal in physics: to show how ...
