Electrons are tiny and constantly in motion. How they behave in a crystal lattice determines key material properties: electrical conductivity, magnetism, or novel quantum effects. Anyone aiming to ...

Scientists had predicted based on theory that shrouded cosmic explosions that go unnoticed can be revealed by their light echoes. Now, astronomers have spotted such an explosion.

Scientists have discovered a way to make molecules sitting on a flat surface rotate together using extremely short flashes of ...

The signal indicated that the event occurred extremely far away. The masses of the objects involved also caught scientists’ ...

A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge ...

Scientists demonstrated X-ray four-wave mixing to track correlated electron motion, revealing how energy and information move inside atoms and molecules. Much of the behaviour of matter arises not ...

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 ...

At SwissFEL, PSI researchers demonstrated a technique known as mode-locking, which allows fully coherent, ultrashort X-ray pulses to be produced. In the photo, several undulator modules are visible ...

Decades in the making, NASA's X-ray timelapse shows a stellar explosion expanding into space at up to 2% the speed of light. Reading time 2 minutes A mind-blowing video shows the remnant of an ancient ...

ESA’s XMM-Newton space observatory has captured Comet 3I/ATLAS in X-ray light. This marks the first X-ray observation of the third interstellar object recorded in our Solar System. The observations ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. A never-before-seen blast from a supermassive black hole was ...

It’s the greatest cosmic murder mystery of the year: How did a black hole destroy a star—and what kind of black hole is the culprit? Normally, so-called “gamma ray bursts,” sudden flashes of extremely ...
