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...
NASA and the Florida Institute for Human and Machine Cognition have jointly developed a new robotic exoskeleton, dubbed the "XI," that could help astronauts in space stay in better physical shape, while also helping humans on Earth walk. The 57-pound wearable device is in essence a robot that fits o...
One of the nine Merlin engines of SpaceX's Falcon 9 rocket suffered what the company called "an anomaly" after the vessel's launch on Sunday. The "anomaly" looks a lot like one of the rocket's nine engines failing in mid-launch, as can be seen in the video below Initial data suggest that Engine 1 l...
The first resupply mission to the International Space Station conducted by a private firm is set to launch Sunday evening. A Falcon 9 rocket carrying a Dragon capsule made by SpaceX are scheduled to take off from Space Launch Complex 40 at Cape Canaveral in Florida at 8:35 p.m. Eastern time. Ahead o...
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...
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...
Nasa's Curiosity rover has begun satisfying the curiosity of mission scientists by sending high-quality images of Mars' surface back to Earth. Although it's only had since Sunday night to collect data, Curiosity has sent a batch of snapshots that are already allowing the NASA team to garner a good d...
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...
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 (...
SpaceX's Dragon space capsule returned to Earth on Thursday, 10 days after it took off into the wild blue yonder to resupply the International Space Station. The capsule touched down in the Pacific Ocean at 11:42 a.m. ET a few hundred miles west of Baja California, Mexico. It will be taken by boat t...
The Dragon was caught by its tail on Friday. The unmanned SpaceX spacecraft, which launched into orbit earlier this week, has successfully docked with the International Space Station, marking a first for a cargo-carrying private spacecraft. The docking was assisted with the station's 58-foot robotic...
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...
