Жизнь во Вселенной Но до сих пор сигналы разумных существ не обнаружены. Стратегия поиска за это время заметно изменилась. Первые работы просто повторяли идею Дрейка в расширенном виде. Затем исследовали другие звёзды и на других частотах, но вскоре поняли, что надеяться на успех можно лишь в том случае, если удастся прослушать всё небо на всех частотах. В компьютерный век это оказалось возможно. В 1992 г. Национальное управление по аэронавтике и исследованию космического пространства США (НАСА) начало проект СЕРЕНДИП (SERE DIP, Search for Ex ra erres rial Radio Emissio from earby Developed I ellige Popula io s — «Поиск внеземного радиоизлучения от соседних развитых цивилизаций»). Проект рассчитан на 10 лет. В нём участвуют несколько обсерваторий разных стран. С помощью параболической антенны диаметром 34 м в Голдстоуне (штат Калифорния) проводится сплошной просмотр неба — полоса за полосой. При выявлении подозрительных сигналов их детальным изучением занимаются более крупные телескопы, такие, как антенна диаметром 64 м в Парксе (Австралия) или 300-метровая чаша в Аресибо на острове Пуэрто-Рико. | |
