The WISE all-sky mid-infrared survey has dramatically improved our ability to detect alien civilizations and to distinguish them from “natural” astrophysical sources.

Wright discusses his team’s efforts to identify so-called candidate Type II civilizations in the Milky Way and Type III civilizations throughout the low-redshift universe.

Because the scope and assumptions of this approach are complementary to those of telecommunication SETI, a null result has the potential to rule out broad classes of proposed resolutions to the Fermi-Hart Paradox, particularly those that invoke organization of advanced alien species across the Milky Way.
