The device is a sensor, and it represents some of the core technology of MC10, a startup that makes flexible electronics. Ghaffari, cofounder and director of advanced technology at the company, isn't at liberty to tell me what, exactly, it senses. It could be temperature, muscle activity, or heart rate.

The sensor's counterpart is another rectangle of silicone. This one encases more traditional semiconductor chips, each about half the size of your pinky nail. Rather than being soldered to a brittle green board that's etched with interconnects, the chips are linked by what appear to be the same wavy, bendable wires. It's not as flexible as the passive sensor because of the chips, but it's still supple enough to bend around my finger. It's the brains of the system, Ghaffari tells me. It receives data from the sensor and then processes, stores, and passes on that information.

Several key conditions came together to create this award-winning shot. These included a dark night, few clouds, an epic auroral display, and a body of water that was both calm enough and unfrozen enough to show reflected stars. The featured skyscape of activity and serenity appeared over Iceland's Vatnajökull Glacier a year ago January, with the Jökulsárlón Iceberg Lagoon captured in the foreground. Aurora filled skies continue to be common near Earth's poles as our Sun, near Solar Maximum, continues to expel energetic clouds of plasma into the Solar System.

This still image was taken from a new NASA movie of the sun based on data from NASA's Solar Dynamics Observatory, or SDO, showing the wide range of wavelengths – invisible to the naked eye – that the telescope can view. SDO converts the wavelengths into an image humans can see, and the light is colorized into a rainbow of colors.
