| Revolutionary microshutter technology hurdles significant challenges Posted: 29 Jul 2014 07:56 PM PDT NASA technologists have hurdled a number of significant technological challenges in their quest to improve an already revolutionary observing technology originally created for the James Webb Space Telescope. |
| NASA-funded X-ray instrument settles interstellar debate Posted: 29 Jul 2014 07:56 PM PDT New findings from a NASA-funded instrument have resolved a decades-old puzzle about a fog of low-energy X-rays observed over the entire sky. Thanks to refurbished detectors first flown on a NASA sounding rocket in the 1970s, astronomers have now confirmed the long-held suspicion that much of this glow stems from a region of million-degree interstellar plasma known as the local hot bubble, or LHB. |
| Weighing the Milky Way: Researchers devise precise method for calculating the mass of galaxies Posted: 29 Jul 2014 07:49 PM PDT Does the Milky Way look fat in this picture? Has Andromeda been taking skinny selfies? Using a new, more accurate method for measuring the mass of galaxies, and international group of researchers has shown that the Milky Way has half the Mass of the Andromeda Galaxy. |
| NASA long-lived Mars Opportunity rover passes 25 miles of driving Posted: 28 Jul 2014 04:22 PM PDT NASA's Opportunity Mars rover, which landed on the Red Planet in 2004, now holds the off-Earth roving distance record after accruing 25 miles (40 kilometers) of driving. The previous record was held by the Soviet Union's Lunokhod 2 rover. |
| Cassini spacecraft reveals 101 geysers and more on icy Saturn moon Posted: 28 Jul 2014 04:15 PM PDT Scientists using mission data from NASA's Cassini spacecraft have identified 101 distinct geysers erupting on Saturn's icy moon Enceladus. Their analysis suggests it is possible for liquid water to reach from the moon's underground sea all the way to its surface. |
