Searching for Technosignatures

NSF's Discovery Files

Humans have always looked up to the sky and wondered about the stars and what life may be out there. Astronomers are using tools such as the U.S. National Science Foundation’s Green Bank Observatory and the Karl G. Jansky Very Large Array to search for radio waves, technosignatures sent from distant stars. David DeBoer, a research astronomer at the University of California, Berkeley joins to explain how Breakthrough Listen is leading this effort and how the Collaboration for Astronomy Signal Processing and Electronics Research is advancing the technology behind it.
