In the quest for extraterrestrial life, the biggest impediment to scientists at the SETI Institute may just be too much noise from Earth. SETI stands for "search for extraterrestrial intelligence" by the way, and it is a non-profit research organization established in 1984 in order to explore, understand, and explain the origin and nature of life in the universe.
There’s so much radio interference these days that any detected signal has to be assumed to be RFI until proven otherwise. Scientifically, taking this skeptical approach is the right thing to do, lest you make a fool of yourself for prematurely declaring triumph in the search for ET. But emotionally, there’s always a tingle of excitement whenever a candidate signal is found.
Several false alarms have already been set off ever since the very first SETI experiment in 1960. Supercluster tells us the long history of humans' search for life outside our planet.
