Could the first confirmed signal from an extraterrestrial source be less a hello than a goodbye? Astrophysicist David Kipping argues as much, and his “Eschatian Hypothesis” reimagines the way ...

As this interstellar object approached its closest point to Earth, a massive radio telescope attempted to sniff out a ...

The first unmistakable signal from another intelligence may not be a cheerful greeting. A growing group of researchers is ...

A new paper posits that advanced alien civilizations may communicate through subtle flashes, like fireflies do on Earth. The ...

An international team of researchers pointed the largest single-dish radio telescope in the world at 3I/ATLAS.

ADVANCED alien civilisations might be talking to each other across the vast reaches of space using a “firefly” technique.

Researchers noted that two other teams conducted independent searches of 3I/ATLAS at different frequencies. Neither group detected credible artificial radio signals. Scientists say the findings ...

Bad news for those hoping interstellar invader 3I/ATLAS is an alien spacecraft as technosignature search turns up empty.

We've all grown up dreaming of aliens landing on the Earth or laser beaming across the sky; well, either way, it's sci-fi and dramatic. But what if th.

Astronomers conducted a radio scan of interstellar object 3I/ATLAS, finding no credible signs of artificial technology, supporting its natural origin.

I/ATLAS is a natural celestial object with all the qualities typical to a comet. It doesn't just belong to our solar system.
