A new SETI study argues that turbulent space weather around distant stars can smear out ultra‑narrow alien radio signals, meaning technosignatures may already have reached Earth.

Astronomers have been scanning the skies for alien radio signals for decades, but so far they’ve heard nary a peep (with one possible exception). But according to a recent study, that could be because ...
