The Allen Telescope Array is composed of 42 six-meter dishes (eventually 350) and is designed for simultaneous radio astronomy surveys and SETI (Search for ExtraTerrestrial Intelligence) observations at centimeter wavelengths. Located about 450 km northeast of San Francisco, it is being built through a partnership between the SETI Institute and the Radio Astronomy Lab of the University of California Berkeley.

In fact, though, the 20-foot-diameter antenna the deer was investigating was just one of 42 identical units that make up the Allen Telescope Array, currently the world's first large-scale telescope meant for the full-time use of the Search for Extra-Terrestrial Intelligence (SETI) project.
