Radio telescopes have long scanned quiet patches of sky for a lone, artificial-sounding ping, but a growing body of research is pushing astronomers to look instead at the loudest neighborhoods in the ...

Green Bank Telescope rules out alien signals in interstellar comet 3I/ATLAS after rigorous scientific deep search.

Since the first Search for Extraterrestrial Intelligence (SETI) experiment in 1960, scientists have been scanning the Milky ...

A group of Chinese scientists is diving deep into the cosmos in search of alien radio signals from the TRAPPIST-1 star system, which might house planets that could support life. This is no small feat, ...

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 ...

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 ...

If so, why haven’t they said hello? The humble residents of this pale blue dot have been on a quest to find an alien civilisation for more than a century. First, it was the “canals” of Mars. Then ...

Scientists found new evidence (or lack thereof) disproving the conspiracy theory that interstellar comet 3I/ATLAS is alien technology.

A new study suggests a novel approach in the long-running scientific endeavor to find intelligent life beyond Earth. Instead of casting a wide, speculative net across the cosmos, researchers from Penn ...

Where are all the aliens? No, I don’t mean microbes on Mars or creatures swimming beneath the ice crusts of Europa or Enceladus, but honest-to-God intelligent aliens, capable of space travel? Corbet’s ...
