Laser-plasma interactions represent a cornerstone of high-energy-density physics, where intense laser pulses interact with solid or gaseous targets to generate plasmas. This process underpins the ...

High-frequency light is useful. The higher the frequency of light, the shorter its wavelength—and the shorter the wavelength, the smaller the objects and details the light can be used to see.

In recent years, the world of optics has undergone a major shift. New research shows how light can be bent, focused, and even changed in color using structures so small they’re invisible to the eye.

In a glimpse of the early universe, astronomers have observed a galaxy as it appeared just 800 million years after the Big ...

Animals with ultraviolet color patterns can be found all over nature. Here’s what we know about what purpose these patterns serve. Scorpions are one of many animals that appear to glow under ...
