Multiple research teams claim to have conclusively demonstrated quantum entanglement, which had been disdainfully dubbed "spooky action at a distance" by Albert Einstein.
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.
The technique, which was able to drop a liquid's temperature by 20 degrees Celsius, could eventually be used for everyday tasks like refrigerating water.
There's 400 percent more light in intergalactic space than sources could produce, say researchers. Could dark matter be the cause?
The first images of Pluto's atmospheric hazes sent back by the New Horizons spacecraft show that mornings there might not be so different from Earth's -- in at least one way.
For decades, physicists thought the hard-to-detect fundamental particles were massless. Not so, Takaaki Kajita and Arthur McDonald discovered, opening new research into the universe's past and present.
An astronaut aboard the International Space Station captures the craft reflecting an Earthly lightning strike in front of a cosmic backdrop.
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.
