Small, Discreet Data Glasses also Correct for Farsightedness

June 9, 2015 9:56 am | by Fraunhofer-Gesellschaft | News | Comments

Data glasses tend to be chunky, unstylish objects, so it’s no wonder they haven’t caught on among general consumers. Researchers have now developed a technology that allows specs to be made in small, unobtrusive designs. The new glasses also correct for farsightedness. While commercially available data glasses often project the image on the edge of the field of view, users of the new model see information precisely where context dictates.

Scientists at Work: Most Days in the Life of an Astronomer aren’t spent at Telescopes

May 11, 2015 10:38 am | by Nicole Estefania Cabrera Salazar, Georgia State University | Articles | Comments

On a telescope at the summit of Mauna Kea in Hawaii, it’s not easy to put in a full night of work. At 14,000 feet, you’re operating at only 60 percent of the oxygen available at sea level, which makes concentrating difficult. Top that off with a shift that begins at 6:30 pm and ends at 6:30 am, and it becomes hard to imagine astronomers working like that year-round. Luckily, most of us don’t have to.

Solar Dynamics Observatory Sees 'Cinco de Mayo' Solar Flare

May 8, 2015 10:02 am | by NASA | News | Comments

NASA's Solar Dynamics Observatory, which watches the sun constantly, captured these images of a significant solar flare — as seen in the bright flash on the left — peaking at 6:11 p.m. EDT on May 5, 2015. Each image shows a different wavelength of extreme ultraviolet light that highlights a different temperature of material on the sun.

Between March and April 2003, researchers used NASA's Hubble Space Telescope to capture detailed images of Saturn's Southern Hemisphere and the southern face of its rings. Saturn is seen here in ultraviolet light. Particles in Saturn's atmosphere reflect

On April 25, 1990, astronauts aboard the Space Shuttle Discovery deployed the Hubble Space Telescope into Earth orbit and launched a new era of astronomical discovery. In its quarter-century in orbit, the world’s first space telescope has transformed our understanding of our solar system and beyond. Now, 25 years later, organizations around the world are joining in a celebration of this remarkable observatory.

Researchers have invented a new technology that can increase the bandwidth of WiFi systems by 10 times, using LED lights to transmit information. The technology could be integrated with existing WiFi systems to reduce bandwidth problems in crowded locations, such as airport terminals or coffee shops, and in homes where several people have multiple WiFi devices.

Largest Structure in Universe a Supervoid 1.3 Billion Light Years Across

Astronomers may have found "the largest individual structure ever identified by humanity." In 2004, astronomers examining a map of radiation left over from the Big Bang discovered the Cold Spot, a larger-than-expected unusually cold area of the sky. The physics surrounding the Big Bang theory predicts warmer and cooler spots of various sizes in the infant universe, but a spot this large and this cold was unexpected.

Galactic Pair: Porpoise or Penguin?

What do you see in this image: a porpoise or a penguin? Amateur astronomers have nicknamed this pretty galactic pair after both of these creatures — the graceful curve of a dolphin or porpoise can be seen in the blue- and red-tinged shape towards the bottom of the frame, and when paired with the pale, glowing orb just beneath it, the duo bear a striking resemblance to a bird or penguin guarding an egg.

Discovered on September 5, 1784, by astronomer William Herschel, the Veil Nebula was once a star. Now, it is a twisted mass of shock waves that appears six times larger than the full Moon in the sky. This Hubble Space Telescope image shows just a small part of the nebula, a region known as the ‘south-eastern knot.’ The entire nebula is about 50 light years in radius, and is located almost 1500 light years away.

New NASA/ESA Hubble Space Telescope images capture a rare occurrence, as three of Jupiter’s largest moons parade across the giant gas planet’s banded face. Hubble took a string of images of the event which show the three satellites — Europa, Callisto and Io — in action. The planet's four moons can commonly be seen transiting the face of Jupiter. However, seeing three of them transiting at the same time is rare.

3-D movies, which require viewers to wear stereoscopic glasses, have become very popular in recent years. However, the 3-D effect produced by the glasses cannot provide perfect depth cues. Furthermore, it is not possible to move one’s head and observe that objects appear different from different angles. Now, researchers have developed a new way of generating high-resolution, full-color, 3-D videos that uses holographic technology.

A new way to process fiber optic signals has been demonstrated, which could double the distance at which data travels error-free through transatlantic sub-marine cables. The new method has the potential to reduce the costs of long-distance optical fiber communications, as signals wouldn’t need to be electronically boosted on their journey, which is important when the cables are buried underground or at the bottom of the ocean.
