Summary:
- The article discusses the installation of a new observatory called the Laser Interferometer Gravitational-Wave Observatory (LIGO) that will be used to search for laser signals from extraterrestrial civilizations.
- The observatory is equipped with highly sensitive detectors that can pick up even the faintest laser signals, which could potentially be used by advanced alien societies for communication or other purposes.
- The SETI (Search for Extraterrestrial Intelligence) Institute is collaborating with LIGO to analyze the data collected, with the goal of detecting any signs of intelligent life beyond Earth.
