The Allen Telescope Array (ATA) is a joint effort of the SETI Institute and the Radio Astronomy Laboratory at the University of California, Berkeley. The ATA is a radio interferometer that is dedicated to cutting-edge astronomical research and a simultaneous search for signals of intelligent, extraterrestrial origin.
An interferometer consists of two or more separate telescopes connected together. An interferometer can consist of two or more telescopes either optical or in this case radio telescopes that combine their signals thus having the power of one single large telescope. A collection of small antennas now costs considerably less than a single, large dish.
The Allen Telescope Array was constructed at the Hat Creek Radio Observatory, 400 km northeast of San Francisco, California and will be composed of 350 antennas at completion. The ATA advances the field of radio astronomy.
The ATA consists of 42 20-foot diameter antennas, each moulded out and mounted on pivots that allow them to swivel and slew to view the entire sky above northern California. (Seth Shostak/SETI Institute)
If any"E.T" responded to us what would they say? perhaps something along these lines" Humanity should have taken better care of their world look at what happened to ours"
