  • Rather than searching for aliens phoning home, scientists are looking for signs of the homes themselves. A new project proposing that galaxy-spanning alien civilizations should generate detectable heat has turned up a few dozen galaxies that hold promise as harbors for life. The new approach, dubbed G-HAT for Glimpsing Heat from Alien Technologies, makes no assumptions about what alien civilizations may be like. Franck Marchis at the SETI Institute in California, and his team, said their preliminary survey suggests that such galaxies are rare, but they are out there.
