Scientists discover low-mass microquasars can accelerate cosmic rays, reshaping theories on high-energy particle origins.

Table-top sources that generate both extreme ultraviolet light and soft X-rays through high-harmonic generation of ultrafast infrared laser pulses look set to perform tasks previously accessible ...

High-powered lasers have transformed the way researchers explore extreme physical phenomena, pushing the boundaries of quantum physics and astrophysics. These lasers, when focused to nearly their ...

On March 15, 2024, a space-based observatory detected bursts of low-energy X-rays from deep in the ancient universe, ...

A massive burst of gamma rays produced by the explosion of a star almost two billion light-years away was so powerful that it changed Earth’s atmosphere, according to scientists. Gamma rays are ...

Rapid X-ray oscillations detected near the innermost orbit of a supermassive black hole could indicate the presence of a nearby orbiter such as a white dwarf ...

At a distance of only 7.8 light-years away ... colleagues used Chandra and XMM to study the amounts of steady X-rays and extreme ultraviolet (UV) radiation—the most energetic type of UV ...
