Search of 100,000 galaxies for advanced civilizations yields no obvious candidates

Using data from NASA's WISE orbiting observatory, a team of scientists say they have found no evidence of the mid-infrared energy emissions we would expect to observe from other advanced civilizations. The research is a significant expansion of earlier work in this area, which looked at only 100 or so galaxies.

"The idea behind our research is that, if an entire galaxy had been colonized by an advanced spacefaring civilization, the energy produced by that civilization's technologies would be detectable in mid-infrared wavelengths - exactly the radiation that the WISE satellite was designed to detect for ot...
