The “Wow!” signal is one of our best pieces of evidence for aliens, but researchers are building a compelling case for a more ...

Astronomers hunting alien signals say turbulent stellar plasma around distant worlds may be scrambling extraterrestrial ...

The findings of a new study may help "explain some of the radio silence we’ve seen in technosignature searches" for alien ...

A new SETI study argues that turbulent space weather around distant stars can smear out ultra‑narrow alien radio signals, ...

The search for extraterrestrial intelligence (SETI) has yet to detect alien technosignatures like radio waves, but the cosmos is vast, and there are plenty of places left to look. New research ...

A new SETI study suggests we may be overlooking alien signals not because they aren't there, but because their own stars are scrambling them before they escape into space. Turbulent plasma and ...

The Search for Extraterrestrial Intelligence (SETI) focuses on finding technosignatures—potential signs of alien technology. If we look carefully, we might have a chance at detecting their ...

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 ...

Radio silence has long puzzled those searching for extraterrestrial intelligence, but the answer might lie much closer to the source of potential signals than previously thought. Conditions around ...

The Deep Space Network (DSN) is just the sort of tool aliens could one-day detect, transmitting from Earth. Credit: NASA/JPL What if the first signal ever detected from an alien lifeform wasn't a ...

Scientists say bad space weather may be one reason alien tech signals have not reached our telescopes in a usable form, after ...

Here's what you'll learn when you read this story: Even the most sophisticated radio arrays have not yet detected any signals that could have possibly been beamed through space by aliens. But maybe we ...
