A team of scientists dug through observations made by NASA's Wide-field Infrared Survey Explorer (WISE) spacecraft, hunting for telltale heat signatures coming from 100,000 galaxies— a strategy suggested by theoretical physicist Freeman Dyson back in the 1960s. "Whether an advanced spacefaring civilization uses the large amounts of energy from its galaxy's stars to power computers, spaceflight, communication or something we can't yet imagine, fundamental thermodynamics tells us that this energy must be radiated away as heat in the midinfrared wavelengths," study co-author Jason Wright, of Pennsylvania State University, said in a statement. "This same basic physics causes your computer to radiate heat while it is turned on." [13 Ways to Hunt Intelligent Alien Life] The team found no smoking guns during this pilot study, known as the Glimpsing Heat from Alien Technologies Survey (G-HAT). "Our results mean that, out of the 100,000 galaxies that WISE could see in sufficient detail, none of them is widely populated by an alien civilization using most of the starlight in its galaxy for its own purposes," Wright said in the statement.

Does anyone remember when Jupiter only had 9 known moons ? It wasn't long ago.
This technology is still in it's infancy. There is so much to discover.
I'm curious how folks on this planet will react when other worldly civilizations are discovered. I don't think it's going to be too much longer...... if I were to guess......within the next two decades.

Didn't folks at NASA make that same prediction? Some time in the next two decades? I hope they are right cuz I want to be here when it happens so I can laugh at the skeptics and say I told them so.

I believe at least one of them did say that. I'm hoping the James Webb Telescope will finally verify that we are not alone.
