Beyond the Blink: Probing Quantum Materials at Attosecond Speeds

Researchers have developed a new spectroscopy method to study ultrafast processes in strongly correlated materials, achieving sub-femtosecond resolution.

Black hole 'particle accelerators' are causing mysterious cosmic rays to rain down on Earth at the speed of light

Black hole 'particle accelerators' are causing mysterious cosmic rays to rain down on Earth at the speed of light

A study uncovered how cosmic objects are sending accelerated particles through space. Jets coming from quasars and supernovae can send dangerous cosmic rays that hit Earth. For the first time, a study showed how the cosmic rays are accelerated to near the speed of light.
