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

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

The first bubble of hot gas seen around another star has been spotted around the "Moth," just 117 light-years away.

Comets are often treated as leftovers, but sometimes the leftovers become the primary focus. That is the case with 3I/ATLAS, only the third known interstellar object seen crossing the solar system, ...

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

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 ...

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