Spitzer space telescope observations reveal expansion rate of the Universe

The size and age of our Universe is not only a critically important issue in cosmology, but is also among the most controversial and delicate of the cosmological questions. Infrared observations made using NASA's Spitzer Space Telescope have now given us the most precise estimate yet of the rate at which our Universe is expanding. The key was not the discovery of a new method for measuring distance. Rather, astronomers discovered how to measure brightness more accurately. The new value for the Hubble constant, good to within three percent, is 74.3 kilometers per second per megaparsec (km/s/Mpc). Read More

Black silicon could boost efficiency of traditional solar cells

Researchers at the Fraunhofer Institute for Telecommunications have developed a system that allows solar cells to effectively harvest energy from the infrared spectrum, tapping into a source of energy that in the past has mostly been out of reach. The new technology, which promises to work well with commercially available solar cells, has the potential of becoming a standard in the solar panels of tomorrow. Read More

New production process promises cheaper infrared lenses

Driving a car in the country at night can be a scary. The combination of poor visibility and animals or other hard to spot obstacles on the road poses an obvious threat to both the car and its occupants. Some luxury models now have the option of forward looking infrared (FLIR) night vision systems, so you can see the animal in time to swerve. Unfortunately these systems are pricey, even as an aftermarket add-on, but that may soon change through the work of researchers at the Fraunhofer Institute for Mechanics of Materials (IWM) in Freiburg, Germany. The researchers have invented a way of bringing down the cost of the infrared lenses in FLIR systems down by 70 percent - opening the way to cheap FLIR cameras for the mass market. Read More

MIT researchers develop all-carbon solar cell

Researchers at MIT have developed a new type of photovoltaic cell made with carbon nanotubes that captures solar energy in the near-infrared region of the spectrum, which conventional silicon solar cells don’t. The new design means solar cell efficiency could be greatly increased, boosting the chances to make solar power a more popular source of energy. Read More

Strain-detecting, carbon nanotube-infused "strain paint"

While wireless sensors for detecting the strain placed on bridges and buildings, such as the SenSpot, are easier and cheaper to install than embedded wired networks of sensors, they still need to be in physical contact with the structure being monitored. Researchers at Rice University have now developed a new type of paint, infused with carbon nanotubes, that could make strain detection of materials in buildings, bridges and aircraft possible without actually touching the material.

Satechi's WTR-A brings budget wireless remote control to Canon DSLRs

With the introduction of smartphone apps like Triggertrap and ioShutter, which allow you to control your DSLR from your phone, you might wonder why anyone would still buy a dedicated remote unit ... until that is, you miss a once-in-a-lifetime shot because you needed the phone for something else at the crucial moment. Sometimes simple is better. The Satechi WTR-A is a budget wireless timer remote for Canon DSLRs. Read More

ESO approves European Extremely Large Telescope

The European Southern Observatory (ESO) council met on Monday in Garching, Germany and approved the European Extremely Large Telescope (E-ELT) program, pending the confirmation of ad referendum votes from the authorities of four member states before the next council meeting. Assuming all goes according to plan, the E-ELT is expected to begin operation early in the next decade. Read More
