Researchers are now looking for advanced alien civilizations beyond the Milky Way [Video]

In context: Radio waves from distant galaxies are too faint to provide meaningful data for potential space observations. However, a sufficiently advanced alien civilization could harness energy in such a way that an entire galaxy could be affected. SETI is looking into it.

Researchers used a powerful ground array for low-frequency radio observations to look for potential signs of life outside the Milky Way. Radio astronomer Chenoa Tremblay of the Search for Extraterrestrial Intelligence Institute (SETI) and astrophysicist Steven Tingay of the International Centre for Radio Astronomy Research recently published a study about their efforts to discover “technosignatures” coming from distant parts of the cosmos.

SETI and other scientific projects searching for intelligent extraterrestrial life usually focus on targets located in the Milky Way. Radio waves coming from external galaxies would be indistinguishable from background noise when looking for …
