| NASA radar images Asteroid 2007 PA8 Posted: 06 Nov 2012 09:29 AM PST Scientists working with NASA's 230-foot-wide (70-meter) Deep Space Network antenna at Goldstone, Calif., have obtained several radar images depicting near-Earth asteroid 2007 PA8. The images were generated from data collected at Goldstone on Oct. 28, 29 and 30, 2012. The asteroid's distance from Earth on Oct. 28 was 6.5 million miles (10 million kilometers). The asteroid's distance to Earth was 5.6 million miles (9 million kilometers) on Oct. 30. The perspective in the images is analogous to seeing the asteroid from above its north pole. Each of the three images is shown at the same scale.  |
| Star formation slumps to 1/30th of its peak Posted: 06 Nov 2012 08:41 AM PST While parts of the world experience economic hardship, astronomers have found an even bigger slump happening on a cosmic scale. In the largest ever study of its kind, astronomers have established that the rate of formation of new stars in the Universe is now only 1/30th of its peak and that this decline is only set to continue.  |
| Quality products from rubber residues Posted: 06 Nov 2012 06:27 AM PST Rubber residues can be downcycled to floor coverings and safety crashpads, and for the first time, also processed into high-quality plastics. A new kind of material makes it possible: the environmentally-friendly material mix is called EPMT, experts say.  |
| New strategy for fingerprint visualization developed Posted: 06 Nov 2012 05:49 AM PST Identifying fingerprints on paper is a commonly used method in police forensic work, but unfortunately it is not easy to make those fingerprints visible. Now, scientists have developed a new approach for making such fingerprints more readily readable.  |
