Allen Telescope Array Starts Search for E.T.

Radio telescope array will seek out new life and new civilizations

It's smaller than originally hoped for, but with 42 radio antennas the Allen Telescope Array, or ATA, is the most advanced structure ever built to look for signs of extraterrestrial intelligence. Following technical delays and cost overruns that left it well short of its planned size, the array is expected to begin its mission full-time this month. It began performing radio astronomy last year but wasn't ready to look for artificial radio signals until now.

”We are doing final calibration, testing, and repairs and expect to begin with the first SETI program by about September 1,” Leo Blitz, director of ATA and the Radio Astronomy Laboratory at the University of California, Berkeley, told IEEE Spectrum.

Each January, the editors of IEEE Spectrum offer up some predictions about technical developments we expect to be in the news over the coming year. You’ll find a couple dozen of those described in the following special report. Of course, the number of things we could have written about is far higher, so we had to be selective in picking which projects to feature. And we’re not ashamed to admit, gee-whiz appeal often shaped our choices.
