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 ...

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

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

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

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

Red dwarfs make up the vast majority of stars in the galaxy. Such ubiquity means they host the majority of rocky exoplanets ...

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

This ship was huge. It was like a city-sized ship. And there was hundreds of beings on board,” said Debbie Solaris, a military veteran and one of six panelists sharing their alien encounters with a ...
