It seems that the frequency of planets able to support life is roughly one percent. In other words, a billion or more such worlds exist in our galaxy alone. That's a lot of acreage, and it takes industrial-strength credulity to believe it's all bleakly barren.
Could it be that the sound from a planetary body is a collective yearning of extraterrestrial intelligence living on such a body, and would it mean that we have to isolate each 'component' sound from its totality to effectively 'understand' what an extraterrestrial being is saying?
It's time for some new predictions! Anything could happen in 2013. Who knows? Maybe the SETI project's radio telescopes will receive an alien transmission and pinpoint the source to that UFO hovering over Donald Trump's head.
The question of whether extraterrestrial life exists (and in particular "intelligent" ET life) is arguably one of the most intriguing questions today. The discovery of ET life would constitute a revolution rivaling the Copernican revolution in magnitude. Here is a brief status report.
Despite any inclination to believe yourself among the brightest bulbs around, new research indicates that even when the universe was considerably younger, there were heavy elements enough to spawn planets that could... spawn life.
With so many places for life to exist, we may be closer to finding E.T. than ever before. Imagine what we'd glean from that encounter. How much more we'll come to know -- not only about life in the cosmos but also about ourselves.
The launch of SETI Live opens the door for anyone to help search for intelligent life on other planets. For the first time ever, data being received by the Allen Telescope Array in Hat Creek, CA will be made public so citizen scientists can scan it for potential signals.
For the first time ever, we awarded the TED Prize to an idea rather than a person: the City 2.0. During this live session we reveal the BIG secret -- the 2012 TED Prize winner's wish to change the world.
A popular theory amongst those who believe aliens have already visited our solar system is that there is evidence of alien technology in ancient architecture, such as the pyramids in Egypt, the Nazca lines in Peru, or Stonehenge in England.
