As per a new study, Dyson spheres around faint stars in the galaxy could offer new techno-signatures clues.

SETI has spent decades listening for a sharp, well-defined radio signal that could indicate it was sent by distant intelligent life. Now researchers believe that space weather could distort and blur s ...

“The universe is not as quiet as we were told.” The line belongs to a dramatic retelling of a disputed signal claim, but it captures a sober scientific problem: the first technosignature humanity ...

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 ...

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 ...

Avi Loeb, who challenged scientists on the true origin of 3I/ATLAS, reckons alien life form will make contact with us soon ...

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