New And Improved SETI

SETI has some glossy new instruments coming on-line. At Harvard University, a survey telescope designed to sweep massive swaths of the sky in a hunt for extraterrestrial laser flashes is becoming a reality.

This impressive antenna farm will be spread over about a half square-mile of terrain
