    In human trials, participants were able to detect Morse-code-like flickering from infrared LED sources and accurately judge the direction of the incoming signals. In a major step toward wearable superhuman technology, researchers have developed contact lenses that allow mice and humans to see in infrared without requiring any power source. The lenses enable simultaneous perception of both visible and infrared light, with applications ranging from security to assisting the visually impaired. The team engineered soft contact lenses embedded with specialized nanoparticles that convert near-infrared (NIR) wavelengths (800–1600 nm) into visible light. These particles emit light in the 400–700 nm range—detectable...

    Explanation: Saturn looks slightly different in infrared light. Bands of clouds show great structure, including long stretching storms. Also quite striking in infrared is the unusual hexagonal cloud pattern surrounding Saturn's North Pole. Each side of the dark hexagon spans roughly the width of our Earth. The hexagon's existence was not predicted, and its origin and likely stability remain a topics of research. Saturn's famous rings circle the planet and cast shadows below the equator. The featured image was taken by the robotic Cassini spacecraft in 2014 in several infrared colors. In 2017 September, the Cassini mission was brought to...
  • Webb Detects 138 Decameter Asteroids in Main Belt

    These asteroids are as small as 10 m across, making them the smallest asteroids ever observed in the main asteroid belt. An artist’s illustration of Webb revealing, in the infrared, a population of main-belt decameter asteroids. Image credit: Ella Maru / Julien de Wit. Asteroid discoveries are essential for planetary-defense efforts aiming to prevent impacts with Earth, including the more frequent megaton explosions from decameter impactors. While large asteroids (=>100 km) have remained in the main belt since their formation, small asteroids are commonly transported to the near-Earth object (NEO) population. “We have been able to detect NEOs down to...
  • Optical Engineers Invent Ultra-Thin Coating That Turns Ordinary Glasses into High-Efficiency Night Vision Goggles

    The Debrief ^ | June 07, 2024 | CHRISTOPHER PLAIN
    A team of scientists has created an ultra-thin coating that can provide high-efficiency night vision to any glass surface, including ordinary reading glasses. Designed using something called a non-local metasurface, the plastic-wrap-thin coating also lets through all of the visible light, allowing users to see perfectly during daytime or at night. Some previous efforts using a non-local metasurface to create a night vision coating have shown limited success. However, those efforts have suffered from severely limited image quality. The inventors of this newest coating say they have broken through that barrier, resulting in a high-definition image visible light image that...

    The Debrief ^ | APRIL 3, 2024 | Christopher Plain
    Scientists say they have created an experimental new high-tech window coating that works similarly to polarized lenses on sunglasses by allowing all of the visible light through while also reflecting unwanted heat. If added to existing buildings and car windows, the new coating could reduce internal temperatures in hotter climates without sacrificing any of the visible light while also reducing energy usage for indoor air conditioning by as much as 30%. The new coating was developed by researchers from Notre Dame University who were looking for a cheap yet viable way to reduce the use of air conditioning in cars...

    Andromeda galaxy in far-infrared. Astronomy has a blind spot in the area of far-infrared radiation compared to most other wavelengths. A far-infrared space telescope can only utilize its full sensitivity with an actively cooled mirror at temperatures below 4 Kelvin (-269 ℃). Such a telescope doesn't exist yet, which is why there has been little worldwide investment in the development of corresponding detectors.In 2004, SRON decided to break this cycle and invest in the development of Kinetic Inductance Detectors (KIDs). Now, researchers from SRON and TU Delft have achieved the highest possible sensitivity, comparable to feeling the warmth of...

    Universe Today ^ | 4/8/2022 | Nancy Atkinson
    The James Webb Space Telescope continues to cool down out at its location at Lagrange Point 2, about 1.5 million kilometers from Earth. Since JWST is an infrared telescope, it needs to operate at extremely low temperatures, less than 40 K (-223 degrees Celsius, -369.4 degrees Fahrenheit). But one instrument needs to be even colder. To operate at peak efficiency, Webb’s Mid-Infrared Instrument (MIRI) must be cooled to a chilly 7 K (-266 C, -447 F). And it will need a little help to reach those frigid temps.Most of the telescope and its instruments rely on JWST’s massive sunshield as...

    It is well known that dogs boast an incredible sense of smell, but new research has uncovered another way our four-legged friends use their famous noses to find their way around. Scientists have discovered what they describe as an "entirely new sense" in dogs, observing how their wet nose tips can be used to sense heat from nearby objects, much like a thermal infrared sensor. The research was carried out by scientists at Sweden's Lund University, along with a team from Hungary's Eötvös Loránd University, who conducted a pair of experiments that uncovered this surprising new canine skill. The Lund...

    The coating flouts the typical trend of hotter objects radiating more lightHotter objects typically glow brighter than cooler ones, making them stand out in infrared images. But a newly designed coating bucks the rule that hotter equals brighter. For certain wavelengths of infrared light, the material’s brightness doesn’t change as it warms, researchers report December 17 in Proceedings of the National Academy of Sciences. Made of samarium nickel oxide, the thin coating “hides temperature information of surfaces from infrared cameras,” and could therefore be used as a privacy shield, says applied physicist Mikhail Kats of the University of Wisconsin–Madison....
  • A nanoparticle injection is all it takes to let these mice see in infrared

    By injecting specialized light-tweaking nanoparticles into a mouse’s retina, that mouse is suddenly and clearly able to perceive near-infrared light — suggesting the same could be possible for us, assuming you don’t mind a needle in the eye. The advance involves what the researchers, from the University of Science and Technology in China, call “ocular injectable photoreceptor-binding upconversion nanoparticles.” In fact, it turns out that these researchers had already created the necessary trickery for a different reason, namely as a molecule for optogenetic triggers that would absorb infrared light (which conveniently penetrates many tissues) and emit visible spectrum light instead....

    Explanation: Cosmic dust clouds ripple across this infrared portrait of our Milky Way's satellite galaxy, the Large Magellanic Cloud. In fact, the remarkable composite image from the Herschel Space Observatory and the Spitzer Space Telescope show that dust clouds fill this neighboring dwarf galaxy, much like dust along the plane of the Milky Way itself. The dust temperatures tend to trace star forming activity. Spitzer data in blue hues indicate warm dust heated by young stars. Herschel's instruments contributed the image data shown in red and green, revealing dust emission from cooler and intermediate regions where star formation is just...

    In 1921, according to the history books, an newly-blind Englishman named James Biggs was feeling threatened by the amount of traffic in his neighborhood. In order to be more visible to motorists, Biggs reportedly painted his cane white. If true, it means the white cane as an aid to the blind is approaching its 100th birthday. Which explains why, in true Silicon Valley fashion, Raghav Ganesh thought the world was overdue for the white cane, 2.0.

    Lockheed has a new modular sensor system for combat aircraft dubbed the "Legion Pod" that aims at plugging a major hole in US air warfare capability. It provides a bolt-on Infrared Search and Track (IRST) system for optically hunting down enemy aircraft, especially stealthy ones, that our radars have trouble detecting. The Legion Pod is pitched as a plug-and-play system that can be rapidly adapted to suit different aircraft and customers needs. Presumably, different sensors could end up being carried in the 18 inch thick pod system, not just the IRST and the data-link alone that the pod was unveiled...

    When we look out at the Universe, our view is pretty consistently dominated by the stars within our own galaxy. Although we know that many interesting things lie beyond — globular clusters, individual galaxies, and rich clusters and superclusters of galaxies — being in the Milky Way makes it very hard to see a great many of them. This is because our own galaxy, from our vantage point within it, dominates a huge fraction of the sky overhead. Image credit: Richard Payne, of Arizona Astrophotography.The plane of the Milky Way itself obscures about a total of 20% of our night sky. What appears...

    SETIÂ’s Colossus by Paul Gilster on May 31, 2013 For the most part, the focus of SETI since Project Ozma has been directed at intercepting signals deliberately sent our way. It doesnÂ’t have to be so, of course, because extraneous signals from a civilization going about its business would also be profoundly interesting, and even a civilization not much more advanced than ours might be throwing off powerful evidence of its existence through the planetary radars it uses to detect potential impactors in its own system. Whether or not the Ohio State WOW! signal was a SETI detection remains unresolved,...

    Finding ET in the Data by Paul Gilster on April 17, 2013 As we saw yesterday, the Infrared Astronomical Satellite (IRAS) has been the source of data for a number of searches for unusual infrared signatures. The idea is to look for the artifacts of advanced extraterrestrial civilizations, under the assumption that a sufficiently advanced culture will be capable of engineering projects that could be detected from light years away. A Dyson sphere, existing either as a completely enclosed star or as a swarm of artifacts around a star, is but one example of such engineering, but it’s a sensible...
