Why NASA observes the Sun in different wavelengths

(Phys.org)—Taking a photo of the sun with a standard camera will provide a familiar image: a yellowish, featureless disk, perhaps colored a bit more red when near the horizon since the light must travel through more of ...

Black silicon can take efficiency of solar cells to new levels

Scientists at Aalto University have demonstrated results that show a huge improvement in the light absorption and the surface passivation of silicon nanostructures. This has been achieved by applying atomic layer coating. ...

Researchers develop mathematical model of flowers' iridescence

(Phys.org)—Nature's ability to create iridescent flowers has been recreated by mathematicians at The University of Nottingham. The team of researchers have collaborated with experimentalists at the University of Cambridge ...

First 'bone' of the Milky Way identified

(Phys.org)—Our Milky Way is a spiral galaxy—a pinwheel-shaped collection of stars, gas and dust. It has a central bar and two major spiral arms that wrap around its disk. Since we view the Milky Way from the inside, its ...

A protein's life, up close and personal

(Phys.org)—An EPFL team has developed a technique for spying on the inner lives of cells. For the first time, scientists have used a near-infrared, light-sensitive biocompatible molecule to mark and observe the activity ...
