QUOTE ST. LOUIS, Mo. -- The quest to detect and study gravitational waves with the NSF-funded Laser Interferometer Gravitational-Wave Observatory (LIGO) is now in the fourth month of its first sustained science run since achieving its promised design sensitivity, project personnel announced at the annual meeting of the American Association for the Advancement of Science (AAAS). ... Now that the LIGO is sensitive enough to detect changes in distance a mere thousandth the diameter of a proton, Marx adds, the science return should be even greater. Recent results from the Swift satellite pinpointing the location of short gamma-ray bursts (GRBs) have also heightened astronomers' interest in the results from LIGO's current observational run. That level of sensitivity is, in my opinion, the most incredible technical achievement since the VLA. The very long gamma ray associated with supernova/hypernova 1996aj should also be of great interest. |

News conference about to start. In the auditorium, they have posters up showing the merger of two black holes.
EDIT: CONFIRMED - Merger of two black holes observed at both observatories 7 milliseconds apart on September 14, 2015. EDIT: They are saying that three solar masses of energy was converted to gravitational waves. The black holes were approximately 36 and 29 times the mass of the sun, the resulting black hole was 62 solar masses. The signal LIGO detected lasted half a second. Event occurred 1.3 billon light years away, in the general direction of the Magellanic Clouds (but far beyond them). |
