The $365 million Laser Interferometer Gravitational-Wave Observatory (LIGO) will begin its first "science run" on 23 August. For 17 days, physicists intend to keep their beams of light on target at LIGO's sites in Louisiana and Washington state for simultaneous data collection. Don't expect startling news, however: According to the latest estimates, LIGO's detectors are still 100 to 1000 times more jittery than their blueprints demand.
