Allen Telescope Array (Image 10)

A wide-band feed horn is at the focus of each of the antennas of the Allen Telescope Array (ATA) in Hat Creek, Calif.

The ATA, which is comprised of a large number of small dishes, is used for radio astronomy observations of our galaxy and other galaxies, gamma ray bursts and transient radio sources, and the search for extraterrestrial intelligence (SETI). The ATA is a joint project of the SETI Institute and the Radio Astronomy Lab at the University of California, Berkeley. Partial operating costs of the array are supported by a grant from the National Science Foundation (AST 08-38262).
