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!

Picture This

This Microcomm balanced mixer circuit board, initially designed for the 18 cm weather satellite band, proved sufficiently broadband to cover the 21 cm hydrogen line. Thus, in the mid-1970s, it found its way into a number of amateur radio telescopes.
