Sagan says many civilizations may exist, urges listening to space
In Boston, astronomer Carl Sagan told a special astronomy gathering that the lack of detected radio signals from extraterrestrials is not proof against life elsewhere. He noted a wall banging from construction nearby but urged continued eavesdropping on the cosmos, estimating a million intelligent civilizations may exist in the Milky Way. He referenced early listening efforts by Americans, Canadians and Russians to detect deep space communications.
