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. |

The neutron star merger is actually bigger news than the black hole mergers, as it just provided the explanation for how half the elements on the periodic table are created, and provided absolute confirmation of how some gamma ray bursts are generated, while establishing with certainty that the speed of gravity and the speed of light are equal. Wow! That's a lot of science from one event!
I'm eager to see more neutron star mergers to provide information on the base rates of such events. And incidentally, I might be able to photograph one of these in the northern skies someday. |
