The method involves stitching together many thin “slices” of light reflecting off an object.

In late winter, the zodiacal light is visible in the evening in the Northern Hemisphere (false dusk) and in the pre-dawn ...

Russian scientists develop high-efficiency solar catalysts for water purification ...

Scientists at the University of Groningen, led by Nobel laureate Ben Feringa and colleagues, have created a new porous material that captures and releases carbon dioxide using only visible light. The ...

Ruthenium-functionalized nanodiamonds generate powerful solvated electrons under visible light, bypassing the deep UV requirement that has limited diamond photocatalysis to laboratory settings.

Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus ...

A lunar eclipse will be visible over the United States on March 3. Here's how to view it.

By squeezing terahertz light beyond its usual limits, researchers have exposed hidden quantum "jiggles" inside a ...

Invisible light beyond the range of human vision plays a vital role in communication technologies, medical diagnostics, and optical sensing. Ultraviolet and near-infrared wavelengths are routinely ...

A new metasurface design lets light of different spins bend, focus, and behave independently—while staying sharp across many colors. The trick combines two geometric phase effects so each spin channel ...

The eclipse travelled over Antarctica, meaning that it visible mostly to penguins, though the path of totality also stretched ...
