Cosmologists are finally beginning to sketch a coherent picture of the universe we cannot see, using exquisitely detailed maps of galaxies, ghostly light and the large scale structure of space itself.

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 ...

Near-infrared light is invisible to humans. And yet, under the right conditions, the human eye can perceive it. Researchers from Poland's International Center for Translational Eye Research (ICTER) ...

Researchers from Japan showed that a single organic crystal converts invisible light into visible colors, emitting red light under ultraviolet irradiation and green light under near-infrared ...

A carbon nanotube transistor turns invisible 940 nm light into both a signal and memory, advancing low-power neuromorphic vision hardware. (Nanowerk Spotlight) When a scene is too dark for a ...
