Their goal is to Increase "red light rejection," which involves rejecting essentially all the light to the left of the monitored UV bandwidths on the electromagnetic spectrum. Supernovae have ...

Credit: NASA/JPL-Caltech NASA’s Europa Clipper spacecraft has completed initial commissioning of its ultraviolet spectrograph (UVS), which will help determine the composition of the atmospheric ...

In addition, we also present an overview of key areas of future research that have the potential to enable the next generation of UV-emitting devices. The electromagnetic spectrum is divided into ...

These flowers are often white or another light shade easily visible at night, and often reflect colors on the UV spectrum that humans can’t see but insects can. These plants may flower during ...

“A physical sunscreen typically acts like a shield, deflecting and/or scattering ultraviolet (UV ... It is a broad-spectrum formula that is also water-resistant (for 40 minutes).” ...

As mentioned, “natural” sunscreen typically contains mineral blockers that sit on top of the skin and deflect the sun’s rays, creating a physical barrier between your skin and UV light.

We report the first detection of the Pb II line at 2203.534 angstrom in three metal-poor stars, using ultraviolet spectra obtained with the Space Telescope Imaging Spectrograph on board the Hubble ...

Available far-ultraviolet spectra from the Hubble Space Telescope Cosmic Origins Spectrograph and optical echelle spectra from MIKE on the Magellan Telescopes enable a comprehensive ionization ...

Water treatment and reuse are fundamental because of the increasing demand for freshwater, especially in agriculture. Accordingly, this study evaluated the effects of turbidity of wastewater processed ...

Abstract: When ultraviolet radiation is absorbed within the cutaneous tissues, it can trigger a number of phenomena that can have detrimental or beneficial consequences to an individual’s health.

Neuroscientists and materials scientists have created contact lenses that enable infrared vision in both humans and mice by converting infrared light into visible light. Unlike infrared night ...
