Как мы поймем, что нашли внеземную жизнь?

Мы давно ищем жизнь за пределами Земли. Часто бывает так, что мы находим некий сигнал, который может указывать на наличие жизни, но он не дает нам стопроцентной уверенности: один и тот же сигнал можно объяснить и небиологическими процессами. В этом видео мы поговорим о том, как повысить уверенность в том, что мы нашли именно жизнь, а также о методах поиска внеземной жизни.
