Because the rims of these craters catch rays of light from the sun, this may provide sufficient illumination for the spectrometer to detect frozen water.

Tubes at the top and bottom are intended to catch these flashes of light and tell scientists both the location and the intensity of the interactions.

Let's jump back a few hours and catch some of that evening light.

Made from a flexible polymer film suffused with fluorescent particles, the prototypes catch only a specific wavelength of light and shoot it to an array of sensors that surround the sheet's edge.

Unfortunately, there isn't one catch-all version of Ubuntu Light that you'll be able to download since it'll need to be tweaked for each device, but it is available to OEMs immediately -- still no word of any devices that will be using it, though.

Such snapshots, which are captured by using pulses of laser light a few femtoseconds long rather than by physically clicking a shutter, are able to catch molecules in the process of reacting together.

The all-carbon formula doesn't need to be thickly spread to do its work, and it simply lets visible light through -- it could layer on top of a traditional solar cell to catch many more of the sun's rays.
