Our earliest astronauts were test pilots; their selection followed strict criteria of age, gender, and flight experience that severely limited participation. Are we in danger of creating another exclusive group of spacefarers?
A team of astronomers, after carefully combing data from NASA's Kepler space telescope, has finally nailed a world that might be similar to our own. But is it inhabited? Finding the answer is not easy.
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.
