A microquasar belonging to our Milky Way galaxy has set records by generating cosmic rays with energy levels never before ...

For the first time, researchers have seen how light behaves during a mysterious phenomenon called 'imaginary time'.

The inner-shell X-ray lasing process is similar to optical lasing, just at a much shorter wavelength. An initial pulse of X-ray photons excites atoms' inner-shell electrons.

Energy from the sun’s rays can cause skin damage and cancers. Sunscreens can absorb or reflect the dangerous UV light. Here’s ...

Is black a colour? Black isn’t in the rainbow, but where does it fit in the colour spectrum? What makes something appear ...

Many displays found in smartphones and televisions rely on thin-film transistors (TFTs) made from indium gallium zinc oxide ...

A new analysis of BL Lacertae by NASA’s Imaging X-ray Polarimetry Explorer sheds light on the emission mechanisms of active ...

Cosmic radiation occasionally contains enormous amounts of energy, but we don’t know why or where this radiation comes from.

At the summit of Cerro Pachón, the Vera C. Rubin Observatory has started its work.

An attosecond—or 0.000000000000000001 second—is no time at all for a person. That is not so for electrons, atoms and molecules, and laser-wielding scientists are revealing the action ...

Quantum sensors have become important tools in low-energy particle physics. Michael Doser explores opportunities to exploit ...
