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?
If the two black holes meet, they could release as much energy as 100 million supernova explosions as they shatter their galaxy, a new study finds.
"Riding Light" traces the movement of a photon traveling away from the sun in a film that translates the speed of light into a human perspective.
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.
Information from the Planck space telescope helped create a stunning new map. It's also shedding light on dark matter and the origins of the universe.
The year gone by brought us more robots, worries about artificial intelligence, and difficult lessons on space travel. The big question: where's it all taking us?
Timey-wimey, wibbly-wobbly: scientists reckon satellites and dead stars could hold the key to the mystery of dark matter.
LED lights are the latest thing in home lighting, using less energy and lasting longer than their incandescent cousins. How do they work? Find out in the latest installment of Appliance Science.
Physicists have built a tractor beam out of lasers that can both repel and attract objects across distances 100 times farther than previously possible.
