Astronomers have developed a new technique to detect the cosmic ultraviolet background radiation that keeps the universe ionized and hot. Their findings provide clues as to why astronomers observe ...

Ultraviolet light is a type of electromagnetic radiation that makes black-light posters glow, and is responsible for summer tans — and sunburns. However, too much exposure to UV radiation is damaging ...

Ultraviolet light has a long history as a disinfectant, and the SARS-CoV-2 virus, which causes COVID-19, is readily rendered harmless by UV light. The question is how best to harness UV light to fight ...

Ultraviolet has very short and energetic wavelengths that are shorter than violet on the visible spectrum. But can people see UV? When you purchase through links on our site, we may earn an affiliate ...

In a recent study published in the Journal of Photochemistry and Photobiology, a team of researchers analyzed the effect of ultraviolet (UV) and violet light of different wavelengths on the virulence ...

Ultraviolet (UV) light is a type of radiation. It has more energy than radio waves or visible light but less energy than X-rays or gamma rays. You can be exposed to UV light via natural sunlight or ...

UV light treatment is a specialised treatment that you have at a phototherapy unit in a hospital. In some rare cases you might have phototherapy at home. This information is about having treatment as ...

Astronomers have developed a way to detect the ultraviolet background of the universe, which could help explain why there are so few small galaxies in the cosmos. Astronomers have developed a way to ...
