| Capturing black hole spin could further understanding of galaxy growth Posted: 29 Jul 2013 08:14 PM PDT Astronomers have found a new way of measuring the spin in supermassive black holes, which could lead to better understanding about how they drive the growth of galaxies. |
| NASA's Chandra sees eclipsing planet in X-rays for first time Posted: 29 Jul 2013 01:16 PM PDT For the first time since exoplanets, or planets around stars other than the sun, were discovered almost 20 years ago, X-ray observations have detected an exoplanet passing in front of its parent star. An advantageous alignment of a planet and its parent star in the system HD 189733, which is 63 light-years from Earth, enabled NASA's Chandra X-ray Observatory and the European Space Agency's XMM Newton Observatory to observe a dip in X-ray intensity as the planet transited the star. |
| Experimental quest to test Einstein's speed limit Posted: 29 Jul 2013 08:19 AM PDT Special relativity states that the speed of light is the same in all frames of reference and that nothing can exceed that limit. UC Berkeley physicists used a novel experimental system -- the unusual electron orbitals of dysprosium -- to test whether the maximum speed of electrons follows this rule. The answer is yes, to tighter limits than ever before. They plan another experiment a thousand times more sensitive, approaching the realm where theory may break down. |
