| The Spitzer photo atlas of galactic 'train wrecks' Posted: 25 May 2011 01:41 PM PDT Five billion years from now, our Milky Way galaxy will collide with the Andromeda galaxy. This will mark a moment of both destruction and creation. The galaxies will lose their separate identities as they merge into one. At the same time, cosmic clouds of gas and dust will smash together, triggering the birth of new stars. To understand our past and imagine our future, we must understand what happens when galaxies collide.  |
| NASA's Hubble finds rare 'blue straggler' stars in the Milky Way's hub Posted: 25 May 2011 11:43 AM PDT NASA's Hubble Space Telescope has found a rare class of oddball stars called blue stragglers in the hub of our Milky Way, the first detected within our galaxy's bulge.  |
| Cosmic explosion is new candidate for most distant object in the universe Posted: 25 May 2011 11:15 AM PDT A gamma-ray burst detected by NASA's Swift satellite in April 2009 has been newly unveiled as a candidate for the most distant object in the universe. At an estimated distance of 13.14 billion light years, the burst lies far beyond any known quasar and could be more distant than any previously known galaxy or gamma-ray burst.  |
| Electron is surprisingly spherical, say scientists following 10-year study Posted: 25 May 2011 10:17 AM PDT Scientists have made the most accurate measurement yet of the shape of the humble electron, finding that it is almost a perfect sphere. The experiment suggests that if the electron were magnified to the size of the solar system, it would still appear spherical to within the width of a human hair.  |
| Mars: Red planet's rapid formation explains its small size relative to Earth Posted: 25 May 2011 10:17 AM PDT Mars developed in as little as two to four million years after the birth of the solar system, far more quickly than Earth, according to a new study. The red planet's rapid formation helps explain why it is so small, say researchers.  |
| New bandwidth management techniques boost operating efficiency in multi-core chips Posted: 25 May 2011 09:00 AM PDT Researchers have developed two new techniques to help maximize the performance of multi-core computer chips by allowing them to retrieve data more efficiently, which boosts chip performance by 10 to 40 percent.  |
| 'Nanowire' measurements could improve computer memory Posted: 25 May 2011 08:08 AM PDT Recent measurements may have revealed the optimal characteristics for a new type of highly efficient computer memory now under development -- nanowire-based charge-trapping memory devices.  |
| Quantum sensor tracked in human cells could aid drug discovery Posted: 25 May 2011 08:04 AM PDT Groundbreaking research has shown a quantum atom has been tracked inside a living human cell and may lead to improvements in the testing and development of new drugs.  |
| Sustainable 'bio-derived' jet fuel industry is achievable Posted: 25 May 2011 08:01 AM PDT Establishing an economically and environmentally beneficial, "bio-derived" Australian and New Zealand aviation fuels industry is a viable proposition, according to a new report.  |
| Posted: 25 May 2011 08:01 AM PDT Scientists have developed a new method of design-independent process monitoring for semiconductor wafer manufacturing. The advance promises to provide semiconductor chip manufacturing cost and productivity savings up to 15 percent, potentially increase profit per chip by as much as 12 percent and ultimately lead to less expensive and higher performing electronics devices.  |
| Brilliant but solitary superstar discovered in nearby galaxy Posted: 25 May 2011 05:40 AM PDT An extraordinarily bright isolated star has been found in a nearby galaxy -- the star is three million times brighter than the Sun. All previous similar "superstars" were found in star clusters, but this brilliant beacon shines in solitary splendor. The origin of this star is mysterious: did it form in isolation or was it ejected from a cluster? Either option challenges astronomers' understanding of star formation.  |
