Scientific paper

Radio astronomers have had no success in the search for extraterrestrial intelligence (SETI). Astronomers are now studying the heavens for signals that intelligent beings might send using lasers. Laser lights have the advantage of directionality, monochromaticity, and coherence. This research, called "optical SETI," looks for optical or infrared pulses with detectors that can pick up a broad spectrum of frequencies. By confining the search to stars similar to the Sun, scientists hope to find evidence of life other than ours.
