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 ...

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 ...

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 ...

Here’s what you’ll learn when you read this story: The Search for Extraterrestrial Intelligence (SETI) focuses on finding technosignatures—potential signs of alien technology. If we look carefully, we ...

Recent research suggests that galaxies with high radio emissions—known as “radio-bright” galaxies—could be home to alien civilizations. This idea, explored in Brian C. Lacki’s study Artificial ...

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 ...
