Rethinking Radio: A New Way to Hear the Universe?

Astronomers have unveiled a novel technique for detecting faint signals from stellar and exoplanetary systems — potentially opening new pathways in the search for extraterrestrial technology and natural astrophysical phenomena alike.

In this episode of SETI Live, host Moiya McTier sits down with radio astronomer Cyril Tasse to explore the method described in Nature Astronomy. How does it work? Why is it different from traditional radio searches? And what kinds of signals could it reveal that we've been missing?

Radio waves from distant stars and planets are incredibly faint and often buried in noise. This new approach rethinks how we process and interpret complex data, potentially improving sensitivity to subtle, structured signals.
