A proposed new mission for Kepler — whose original exoplanet hunt stalled this past May when the second of its four orientation-maintaining reaction wheels failed — has advanced to a NASA vetting stage called "senior review," agency officials announced to
Scientists created the new video of Saturn's vortex from 128 images snapped by NASA's Cassini spacecraft in December 2012. It's the highest-resolution movie yet obtained of the giant hexagon, which is about 20,000 miles wide, researchers said.
Scientists have captured the best view yet of how gamma-ray bursts, the most powerful explosions in the universe, are shaped by extreme magnetic fields around black holes.
Soon, we'll know who among the applicants on a one-way trip to Mars makes it into the second round. It's a one-way ticket, but not to worry: you’ll live there longer than back home on Earth. After all, on Mars you can’t get hit by a car. One thing is cert
Venus is now the showiest it will be for all of 2013 and 2014 in either the evening or the morning sky. The planet is so bright that you can spot it in a clear blue sky before sunset, if your eye lands on the right point in the south-southwest.
Gliese 581g is an extra-solar planet that was discovered in 2010, but quickly cast into doubt by other studies. The original discoverers then published a follow-up paper in 2012 defending their find.
NASA's Cassini probe has captured the highest resolution video yet of Saturn's odd, hexagon shaped jet stream that spins around the gas giants north pole.
For decades, the space race was seen as being mostly about national pride. Getting there first mattered most, whereas pushing the frontiers of science and technology took a close second.
Scientists think the moon coalesced out of material blasted into space when a large object slammed into the proto-Earth in the solar system's early days. Determining the composition of Venus could help explain how this mega-collision went down.
Voyager 1 sent back 'tones' recorded by a plasma wave instrument showing the change as the craft crossed over from the heliosphere to interstellar space.
NASA's Solar Dynamics Observatory was treated to another lunar transit on Dec 2, 2013. The SDO team compiled the very best views from different imagers onboard the spacecraft.

Apollo astronaut Al Worden, looking to keep the 'right stuff' forefront in the public's eye, has recreated his iconic NASA-issued blue flight jacket down to the last button.
The U.S. Air Force’s secretive X-37B space plane program launches its third mission, OTV-3, on Dec. 11, 2012 using a United Launch Alliance Atlas 5 rocket. The mission marked the first reflight of an X-37B robotic space plane.
This cluster of stars seen in this space wallpaper is known as Messier 15. It is located some 35,000 light-years away in the constellation of Pegasus (The Winged Horse).
Mustaches were everywhere. On the balloons, face-painted on children and of course, on the face of celebrity astronaut Chris Hadfield himself when he showed up at the book signing.
