Bill Nye and The Planetary Society want to propel a spacecraft by bouncing the sun's photons off it. The first test of such a craft will take place this May.
There's 400 percent more light in intergalactic space than sources could produce, say researchers. Could dark matter be the cause?
What's in a single second? An awful lot, depending on when and where you are in the universe. CNET's Eric Mack ponders the value of Tuesday's extra leap second.
The experimental LightSail spacecraft has lost communication with Earth due to a software glitch. So far, attempts to initiate a reboot have been unsuccessful.
The Planetary Society gets ready to launch its LightSail -- which travels via photon bombardment -- with the help of a Kickstarter campaign.
The search giant pulls an about-face and the wireless carrier puts on a dog-and-pony show for April Fools' Day. Also: Microsoft's MS-DOS Mobile, Motorola's premium selfie stick and Samsung's smart knife.
With no pesky clouds to get in its way, the European Space Agency's Proba-2 satellite captures a stunning view of the moon blotting out the sun.
Using Intel's silicon photonics chips, Fujitsu demonstrates how fiber-optic links can replace copper wires to handle PCI Express data transfer. The result: a machine that's easier to keep cool.
Researchers have achieved the first ever pictorial evidence that light can simultaneously behave as a particle and as a wave.
New research might shed light on how we got here by demonstrating that chemical components of our DNA could be produced in the brutal conditions of space.
