Are We Alone? It's a fundamental question, which has haunted humankind since first we realized that the points of light in the night sky are other suns. Today we have the technology to seek a definitive answer! The SETI League, Inc. is participatory science. Founded in 1994, we are the international grass-roots organization dedicated to privatizing the electromagnetic Search for Extra-Terrestrial Intelligence. Together, fifteen hundred members in five dozen countries on all seven continents are keeping alive the quest for our cosmic companions. Join Us!

SETI is a science, not simply a screensaver!
