New mechanism of photoconduction could lead to next-generation excitonic devices

Shown here is the crystal structure of molybdenite, MoS2. When hit with a burst of laser light, freed electrons and holes combine to form combinations called trions, consisting of two electrons and one hole (represented here by orange and green balls). (Credit: Jose-Luis Olivares/MIT)

NASA’s Orion capsule floats inside US Navy ship

A test version of NASA's Orion capsule floats in the rear of the USS Anchorage during a recovery drill off the coast of California September 15, 2014. Orion is NASA's next exploration spacecraft, designed to carry astronauts to destinations in deep space, including an asteroid and Mars. Picture taken September 15, 2014.

How big data is fueling a new age in space exploration

A few major factors will drive exponential growth in the amount of terabytes falling on us from the skies over the next couple of decades: the increasing speed of commercial satellite deployment, implementation of faster communication technology, and the onset of interplanetary missions.

The difficulty of using the Doppler shift to measure the wobble of a star

One of the biggest advances of astronomy in the past decade has been the discovery of planets orbiting other stars, known as exoplanets. But just how many exoplanets have been discovered? According to the Extrasolar Planet Encyclopedia, a semi-official catalog based in Europe, there were as of the end of September last year 990 confirmed exoplanets and 2,321 candidate exoplanets.
