| Saturn and Jupiter: X-ray laser spies deep into giant gas planets Posted: 11 Mar 2014 07:58 AM PDT Using DESY's X-ray laser FLASH, researchers took a sneak peek deep into the lower atmospheric layers of giant gas planets such as Jupiter or Saturn. The observations reveal how liquid hydrogen becomes a plasma, providing information on the material's thermal conductivity and its internal energy exchange -- important ingredients for planetary models. |
| Possible evidence for dark matter particle presented at UCLA physics symposium Posted: 10 Mar 2014 06:23 PM PDT Dark matter, the mysterious substance estimated to make up approximately more than one-quarter of the mass of the universe, is crucial to the formation of galaxies, stars and even life but has so far eluded direct observation. At a recent UCLA symposium attended by 190 scientists from around the world, physicists presented several analyses that participants interpreted to imply the existence of a dark matter particle. The likely mass would be approximately 30 billion electron-volts, said the symposium's organizer. |
