The exoplanet 51 Pegasi b lies some 50 light-years from Earth in the constellation of Pegasus. It was discovered in 1995 and will forever be remembered as the first confirmed exoplanet to be found ...

Radio astronomy opens a window onto the invisible universe. While our eyes can detect visible light, countless objects in space emit radiation at much longer wavelengths, in the radio portion of the ...

Ultraviolet (UV) light has higher energy photons than visible light and, thus, has more applications. Researchers have now developed a brilliant innovation -- a solid-state material that can stably ...

While many people have noticed excessive screen time can result in tired feeling eyes and may affect sleep, a new study questions the role of blue light in this phenomenon. Blue light is part of the ...

In a new study published in Science, researchers have developed a new method for detecting infrared light by changing its frequency to a corresponding frequency in the range of visible light.

Rather than using the millions of pixels normally found in 3D imaging cameras, a team of scientists from Glasgow University have cut that down to a single, light-sensing pixel, not only making the ...

Capturing photos beyond the visible spectrum is challenging and requires special gear, but the creative payoff is worth it. Here are some of my favorite infrared shots and tips to get you started.

Tired of having to reach for your night-vision goggles when you want to track someone’s heat signature after dark? Well, biotech may someday come to the rescue for all of you aspiring spies. Because ...
