Fast detector for a wide wavelength range

Free-electron lasers are extremely versatile research tools because their intense, super short light flashes permit a closer look at new materials and even biological molecules; thus, allowing effects to be observed that ...

Engineers' nanoantennas improve infrared sensing

(Phys.org) —A team of University of Pennsylvania engineers has used a pattern of nanoantennas to develop a new way of turning infrared light into mechanical action, opening the door to more sensitive infrared cameras and ...

As seen from space: Mt. Etna boils over

Italy's Mount Etna has turned on again, spewing lava and gas in its first big eruption in 2013. The volcano is one of the most active in the world, and is Europe's tallest active volcano, currently standing about 3,329 m ...

Dawn craft to depart asteroid for dwarf planet

One asteroid down, one to go. After spending a year gazing at Vesta, NASA's Dawn spacecraft was set to cruise toward the most massive space rock in the asteroid belt between Mars and Jupiter—a voyage that will take nearly ...

RIT leads development of next-generation infrared detectors

Cheaper, larger and better infrared detectors grown on silicon wafers could give more scientists access to infrared astronomy and further spur the hunt for exoplanets and the study of the universe's acceleration. Closer to ...

Image: A storm of comets around star Eta Corvi

(Phys.org) -- This artist's conception illustrates a storm of comets around a star near our own, called Eta Corvi. Evidence for this barrage comes from NASA's Spitzer Space Telescope, whose infrared detectors picked up indications ...
