Since 2012, the SETI Institute’s Allen Telescope Array in northern California, near Mt. Lassen, has been observing all reported Kepler candidate exoplanets in search of signals from extraterrestrial technological civilizations. This search is looking for patterns in frequency and time that could indicate an 'engineered' signal rather than natural radio emissions. The quiet, terrestrial microwave window from 1 to 10 GHz (where emission from astrophysical sources is minimum) is split into nine billion, narrow, one Hertz channels that are explored by automated, signal processing systems. For almost a month, the ATA has been focusing on the Kepler-186 system, with the Earth-size Kepler-186f in the habitable zone. The ATA has observed all frequency channels from 1 to 10 GHz twice. To date, all signals that have been detected can be attributed to Earth's own technology. At the distance of Kepler-186 (about 500 light years), a signal would have to have an effective, isotopic radiated power that is 10 to 20 times as powerful (depending on the frequency) as the signal from the planetary radar transmitter on the Arecibo Observatory, Earth's strongest transmitter.

Мда, что-то меня перспективы поиска ВЦ современным оборудованием не очень вдохновляют.
А анализ атмосферы может выявить деятельность техногенной цивилизаци?
Подтверждают ли Кеплеровцы кандидаты с помощью телескопа или же работа по подтверждению ложится на земные обсерватории? Какой примерно процент неоткрытых планет м.б. в данных Кеплера?
