After initially revealing its new Ativ Book 9 Lite ultraportable PC in June, Samsung on Monday announced that it is now accepting preorders for the device, which will be available in the U.S. on July 28 for $799.99. Weighing 3.5 lbs. and measuring less than an inch thick, the Ativ Book 9 Lite offers...
After launching Graph Search into beta earlier this year, Facebook on Monday announced that it is now beginning to roll the feature out to everyone who uses the social network's U.S. English version. Graph Search lets users perform searches on the social network that combine phrases -- "my friends i...
The line separating the mobile and desktop computing worlds has become increasingly blurred in recent months, and HP on Monday unveiled a brand-new all-in-one PC that continues that trend. Announced during its HP World Tour event in Beijing, the HP Slate 21 tablet is powered not by Windows but by Go...
Buoyed by the recent success of its Mars rover Curiosity, NASA announced plans to launch a new robotic science rover in 2020. It's also eyeing the possibility of a manned expedition just a decade later. "The Obama administration is committed to a robust Mars exploration program," NASA Administrator ...
Just after 11 p.m. on Aug. 15, 1977, while pointing toward the constellation Sagittarius, Ohio State University's Big Ear radio telescope picked up a mysterious transmission that would very soon make history. For 72 seconds, the Big Ear was able to listen to that signal, which has since come to be k...
Of all the space objects humans have come across so far, asteroids are surely among the more anxiety-producing examples, thanks to their recurring habit of barreling past our planet at terrifying speeds and uncomfortably close proximity. However, it just may be that asteroids are our friends, a new ...
Astronomers have wondered for centuries about the possibility of Earth-like planets in the neighboring Alpha Centauri star system, but only recently did their ongoing search bear fruit. European astronomers have discovered a planet with about the mass of Earth orbiting a star in Alpha Centauri. Obse...
Astronomers have long suspected that Jupiter undergoes more frequent collisions with space objects than we know, but this past Monday one apparently occurred that was so dramatic as to even be visible with amateur telescopes here on Earth. Wisconsin-based amateur astronomer Dan Peterson first repor...
Luke Skywalker's fictional home planet Tatooine in the Star Wars films was perhaps most memorable for its two suns, but astronomers working on NASA's Kepler mission recently discovered something much like it here in our own galaxy. The discovery -- announced at a recent International Astronomical Un...

Following the most complex landing ever attempted on Mars, NASA's most advanced Mars rover to date landed on the Red Planet at 10:32 p.m. PDT on Sunday. Dubbed "Curiosity," the one-ton, car-sized rover had been in flight for 36 weeks. Its complicated touchdown -- including the final severing of the ...
There's been considerable debate over the existence of Gliese 581g ever since the discovery of the "Goldilocks" planet was first reported nearly two years ago, but new research claims to provide additional evidence that the potentially habitable "super-Earth" really is out there. The prospect of the...
Pluto may no longer be considered a true planet following its official reclassification in 2006, but that doesn't appear to be stopping the tiny dwarf planet from amassing a considerable number of celestial "followers." Just this week, in fact, a team of astronomers using NASA's Hubble Space Telesco...
Mention the words, "splitting the atom," and most people will automatically think of nuclear fission, bombs and radioactivity. Recently, however, physicists at Germany's University of Bonn not only managed to "split" an atom but also put it back together again. "The fact that atoms, photons and mole...
The planet Venus will create a rare spectacle on Tuesday when it passes directly in front of our sun, creating an image for viewers on Earth that won't be repeated until the year 2117. Known as "the 2012 Transit of Venus," the nearly seven-hour journey will begin at 3:09 p.m. Pacific Daylight Time (...
A giant but unseen planet may lurk on the outer edge of our solar system, making its presence known only by disrupting the orbits of nearby celestial objects, according to Rodney Gomes, an astronomer at the National Observatory of Brazil. Astronomers have long observed that a group of small, icy bo...
When the SpaceX Dragon capsule blasts off from Cape Canaveral Air Force Station atop the company's Falcon rocket Saturday morning, it will be doing more than just setting off on another cargo-laden trip to the International Space Station. Rather, as the very first commercial attempt ever to fly to t...
Today's hard drives may be smaller, faster, cheaper and more capacious than their predecessors, but the need for ever-tinier components is making it difficult to keep improving them. Therein lies at least part of the motivation behind biocomputing -- in which microscopic biological molecules are bei...
It may have been a "bad moon" rising in the famous 1969 song by CCR, but this weekend's full moon could well inspire predictions for trouble of a similar kind. That's because it's this year's "supermoon" -- the full moon that occurs when the moon is closest to Earth -- and supermoons are often belie...
A technical issue disrupted 4G LTE network service from Verizon Wireless for some customers between late Tuesday and late Wednesday, but the issue is now resolved. That's according to the company, which issued only a terse statement on Thursday morning. The term "outage" is "not entirely accurate" a...
