Scientists say they've located the first definitive proof of a comet hitting Earth: a diamond-studded pebble they've named after legendary female philosopher-scientist Hypatia of Alexandria.
New York-based startup HEVO Power is working with New York University to develop stations that will resemble parking spots with manhole covers. They will enable charging without the need for a plug.
Originally given a 1-in-300 chance of hitting Earth -- 50 percent higher than the average for all other near-Earth objects located to date -- 1950 DA has had its odds reassessed. Fortunately it's not expected to arrive for another 866 years.
Last month, scientists conducting experiments at the National Ignition Facility witnessed, for the first time ever, a fusion reaction that produced more energy than it consumed. It's a significant milestone towards a long-sought-after goal.
NASA's Cassini spacecraft has detected propylene, a chemical used to create food storage containers and other plastic items, on Saturn's largest moon. It's the first time this chemical has been found anywhere outside of Earth.
World Space Week 2013 is all about what many consider the Next Frontier: the planet Mars.
Capturing a smaller space object that temporarily enters Earth's orbit could be a lot easier and cheaper while still providing valuable data, say proponents.
Using data from space telescopes, including the now-sidelined Kepler, astronomers have identified cloud structures on Kepler-7b, a "hot Jupiter" exoplanet that was one of the first discovered.
Maybe it’s truer and more useful to marvel at how we very nearly destroyed ourselves after discovering an unstable new energy source, then figured our way out of it.
Released today (Sept. 27) after an all-night session, the summary document of the UN panel's forthcoming report declares that the proof of climate change is "unequivocal" and that human activity is "extremely likely" to be at fault.
Analysis of the first scoop of topsoil picked up by NASA's Curiosity rover reveals a composition that includes two percent water. It could mean one less worry for future human visitors.
The tragic event compelled nonprofit tech company Ushahidi to create a rough draft of a tool that eventually can be used by even the simplest cell phones. They've posted the code online in hopes that others will help finish it.
For the first time, a new computer model links climate change to the increased frequency and strength of storms. Scientists estimate the number could increase by as much as 40 percent in the eastern US by 2070.
Thanks to the efforts of over 83,000 volunteer citizen scientists around the world participating in the Galaxy Zoo 2 project, the latest catalog of galaxy data is 10 times larger than any previous catalog of its kind.
To test the effects of microgravity on astronauts traveling on extended space missions, the agency will pay qualified candidates who are willing and able to stay (mostly) horizontal for 70 days straight.
