Researchers have developed a novel experimental platform to measure the electric fields of light trapped between two mirrors ...

The core of the Phoenix cluster is shown across the whole electromagnetic spectrum. The bright purples represent X-rays produced by the hot gas, and the dashed purple outlines show regions where this ...

For the first time, researchers have been able to measure the quantum state of electrons ejected from atoms that have absorbed high-energy light pulses. This is thanks to a new measurement technique ...
