SEVENDIP, which stands for Search for Extraterrestrial Visible Emissions from Nearby Developed Intelligent Populations, was a project developed by the Berkeley SETI Research Center at the University of California, Berkeley that used visible wavelengths to search for extraterrestrial life's intelligent signals from outer space.
|
|
Between 1997 and 2007, SEVENDIP employed a 30-inch automated telescope located in Lafayette, California, to scan the sky for potential optical interstellar communications in the nanosecond time-scale laser pulses. Another instrument was mounted on Berkeley's 0.8-meter automated telescope at Leuschner Observatory. Their sensors have a rise time of 0.7 ns and are sensitive to 300 - 700 nm wavelengths.
|
|
The target list included mostly nearby F, G, K and M stars, plus a few globular clusters and galaxies. The Leuschner pulse search examined several thousand stars, each for approximately one minute or more.
