Welcome!

The Allen Telescope Array (ATA) is a radio interferometer in development in northern California, roughly 290 miles northeast of San Francisco, at the Hat Creek Radio Observatory. The ATA is jointly managed by the UC Berkeley Radio Astronomy Lab and the SETI Institute. The ATA currently has 42 dishes and has a goal to expand to 350 dishes. Major funding for the Allen Telescope Array development, construction and management has come from the Paul G. Allen Family Foundation. Science program support is provided by the National Science Foundation University Radio Observatories program.
