Images from the NASA Spitzer Space Telescope have been used to create a staggering 20-gigapixel panorama, encompassing more than half of the galaxy’s stars. The vista was created from more than a decade’s worth of infrared images, and will be used to help further our understanding of the structure and formation of stars in the Milky Way.  Read More

Could it one day be possible to generate electricity from the loss of heat from Earth to outer space? A group of Harvard engineers believe so and have theorized something of a reverse photovoltaic cell to do just this. The key is using the flow of energy away from our planet to generate voltage, rather than using incoming energy as in existing solar technologies.  Read More

Volvo Driver State Estimation uses a dash-mounted infrared sensor

Back in the days of black-and-white newsreels, an inventor came up with a bell on a collar that rang whenever a motorist wearing it nodded off. Since this is the 21st century, Volvo is developing a high-tech version of this gadget. It uses face recognition technology to let a car know when the driver is tired or inattentive, so appropriate action can be taken.  Read More

Various institutes around the world have long touted the potential of breath testing as a form of early and non-invasive disease detection. Now a research team from Australia's University of Adelaide has developed a new kind of laser with the ability to detect low concentrations of gases, opening up even more possibilities for disease diagnosis and other applications such us measuring the concentration of particular greenhouse gases in the atmosphere.  Read More

The FLIR ONE is a slide-on attachment that gives iPhones thermal imaging capabilities

FLIR Systems, Inc. announced two new products at CES designed to put thermal imaging into the hands of consumers. The first is a new, consumer-level infrared thermal camera sensor, while the second is a slide-on attachment for Apple iPhone 5 or 5s smartphones that makes use of said sensor. Both could be used to locate lost pets in the dark, look for energy leaking from your house, or to watch for wildlife.  Read More

Vigo collects information on a user's blinks and body movements and alerts them to when th...

We've seen technology developed to monitor a driver's eyes for drowsiness, alerting them when their focus might be lapsing. The Vigo wearable energy gauge works on a similar principle, yet aims to expand this to other everyday tasks that are likely to induce those heavy eyelids.  Read More

Comparison of Kepler-7b and Jupiter (Image: NASA)

"How's the weather?" has just become a topic of interstellar conversation. Using data from NASA's Kepler and Spitzer space telescopes, astronomers have mapped the first clouds discovered on an extrasolar planet. Not only does this technique give us an interesting bit of pure science, it could also be applied in the search for more earth-like planets according to NASA.  Read More

The new system being tested on the A6 highway, near Madrid

According to scientists at Spain's Universidad Carlos III de Madrid (UC3M), approximately five percent of vehicles on the road are responsible for about 90 percent of toxic vehicle emissions. Short of pulling each and every car over to analyze its tailpipe output, though, how does one go about identifying the offenders? Well, the UC3M researchers have helped design a system that images the emissions of individual vehicles in real time, on highways up to three lanes wide.  Read More

NASA will be putting another eye on potentially dangerous asteroids in September when it reactivates the retired Wide-field Infrared Survey Explorer (WISE). The space telescope, which was deactivated in 2011, will use its infrared instruments to carry out a survey of near-Earth asteroids that may pose a threat to our planet.  Read More

Here’s good news for all you philatelists out there – scientists have discovered an easier new way of detecting counterfeit rare stamps. Unlike some existing methods, it doesn’t require the destruction of any part of the stamp, and can be done quickly by anyone who has access to the necessary equipment.  Read More
