E.T. could be phoning home — but we’re not hearing the call. A new study published in The Astrophysical Journal argues that “space weather” could be distorting incoming transmissions from ...

The researchers who scan the skies for radio signals from extraterrestrials are now rethinking their approach.

We may be missing alien radio signals because they have become smeared beyond the narrowband detectors that SETI utilizes, a new study suggests.

Assuming intelligent aliens know how to harvest energy from stars, would humanity be able to spot these high-level structures?

Stellar plasma can smear alien radio signals before they escape their star system, making them harder for astronomers to detect.

A new psychedelic retreat calling itself a “SETI for the mind” aims to establish two-way communication with the nonhuman entities people encounter while tripping on DMT.

Ever since physicist Freeman Dyson first proposed the concept in 1960, the "Dyson sphere" has been the holy grail of ...

In Amiri’s calculations, Dyson spheres around white dwarfs tend to produce cooler, fainter thermal emission that peaks in the near- to mid-infrared, while M-dwarf cases can radiate more strongly but ...

Chalk up another victory for “Conan the Bacterium”—a rugged germ that fresh research suggests could conquer the solar system.

The guy pouring my beer in Anchorage told me that he knew there was no truth to decades-old rumors about a research facility 200 miles to the northeast. Nobody was up there talking to aliens or ...

A new study shows that stars with low magnetic activity are likely to support exoplanetary systems, making the hunt for these ...
